A 7-year-old boy without any antecedent presented a traumatic dissection of the vertebral artery with subarachnoid haemorrhage. After a conservative treatment, the morphology of the vertebral artery became normal and the boy was asymptomatic. Four months later, a rebleeding occurred on the same vertebral artery, whose morphological review was normal. Mechanisms and cases of rebleeding in the literature are discussed. An inflammatory vasculopathy was suspected and discussed.

She was admitted for confusion and disorientation in a context of high fever and diarrhoea. After two surgeries, the evolution was finally good with a combination of antibiotics (amoxicillin and clindamycin). Chronic subdural hematoma is a potential site for bacterial infection. Our case suggests that C. fetus infection should be suspected in elderly patients presenting with fever and enteritis. The frequency of such cases may be underestimated, due to the difficult diagnosis of C. fetus. It is also suspected that C. fetus could play a role in the recurrence of hematoma, because of its vessel tropism. PMID: 22154423 [PubMed - as supplied by publisher] (Source: Neuro-Chirur...

The surgical approach requires a thorough preoperative reflexion based on magnetic resonance imaging, in order to understand the site of origin and the vascular pedicles of the tumor. Surgical approaches to the frontal horn, temporal horn and atrium are successively described.

The mean age was 33 years with a large proportion of children (79/284). CLINICAL PRESENTATION: The mean duration of symptoms was short in time (2 months). The revelation was incidental in 10% of the cases ; for symptomatic lesions, raised intracranial pressure (ICP, due to hydrocephalus) and neuropsychological signs were the most frequent. Only one third of the patients had no CSF disorder. HISTOPATHOLOGY: The two most frequent tumors were meningiomas (40 cases, 15%) and neurocytomas (35 cases, 13%).

The LV is covered by white matter with important functional role in the dominant hemisphere. Lateral wall of the frontal horn is covered by the inferior occipitofrontal fasciculus (IOFF) and its roof by the corpus callosum (CC). The body of the LV has the same cranial relationship and is covered laterally by fibers of internal capsula and arcuate fasciculus; its lower part is in relationship with the body of the fornix.

They are often clinically silent, incidentally discovered at autopsy. These symptoms are related to big volume. They are attached to the septum pellucidum, leading to hydrocephalus by Monro foramen obstruction. Overall mean age at diagnosis is 39 years with more males than females. At CT-scan, subependymoma shows a slightly low attenuation compared to gray matter. There is no or mild enhancement following contrast injection. On MR T1-weighted imaging, subependymoma is isointense and hyperintense on MR T2-weighted imaging. Intramural calcification...

Their diagnostic features are different in children, especially in infants and even more so in the fetus. The main surgical problems are the risk of bleeding and of hydraulic complications. From an oncological perspective, the main tumor types are choroid plexus tumors, subependymal giant-cell astrocytoma, and low-grade gliomas. The developmental outcome of these patients is often poor, on account of severe intracranial hypertension and young age at diagnosis. PMID: 22024608 [Pu...

If stereotactic techniques are not in the foreground for the management of lateral ventricle tumors, stereotactic biopsies can be very useful in case of atypical, clinical or radiological presentation of the tumors and radiosurgery can help in case of evolution or re-evolution of tumors after resection. In these cases, stereotactic procedures are very safe. Modern technical evolutions allow the optimization of the stereotactic procedure but also to mix robotic with endoscopic techniques in order to offer new surgical perspectives.

Although these neoplasms are easily detected with computed tomography (CT) and magnetic resonance imaging (MRI), both techniques are relatively unspecific in identifying the type of tumor. However, few imaging patterns are specific for a particular pathological process and useful conclusions can be made from the morphological appearance of the lesion, its location and enhancement pattern. The aim of this article was to review and illustrate the CT and MRI findings of a wide spectrum of tumors of the lateral ventricle.

Mean age was 32.6 years. There was a male predominance (20/35). Most frequent clinical signs were neuropsychological disturbances and intracranial hypertension. On imaging, these tumors concentrate central calcifications in more than half of cases. Main locations were frontal horn and corpus of lateral ventricle (82%). Uneventful postoperative course was recorded in 52% of cases. Immunoreactivity against neuron-specific enolase (NSE), synaptophysin, S100 protein, Microtubul Associated Protein de type 2 (MAP2) and calcineurin confirms the neuronal nature of the neoplasm.

The diagnosis is often mentioned due to the delayed onset of gait disturbance and slower psychomotor performance. The CT-scan confirms the diagnosis by showing an enlargement of the ventricles. In case of symptomatic hydrocephalus, a ventriculo-peritoneal shunt is often required. The authors report a rare case of chronic hydrocephalus presenting with visual symptoms, due to the delayed mobilisation of a surgical clip with direct mass effect over the anterior optic pathways. The treatment of hydrocephalus led to a rapid and complete regression of symptoms. PMID: 21992996 ...

Due to the paucity of neurological signs and the patient's advanced age, she was managed conservatively; 8months later the cyst resolved completely. We discuss the potential factors involved in the pathogenesis and the therapeutic options for this uncommon cervical entity.

Anatomopathology showed a dermoïd cyst. Five years later, he presented local recurrence of the dermoïd cyst with intracranial extension through a bifid crista galli. We conclude that to avoid recurrence, the removal of the nasal cyst and sinus tract must be followed to its dural attachment. A transfacial approach can be associated with frontal craniotomy, which can provide adequate exposure for complete removal of the intracranial component of the cyst and sinus tract. A literature review was performed.

CT and MRI anatomical imaging objectified a frontal osteolytic tumor respecting the osseous external table but compressing the superior sagittal sinus. Total en bloc resection of the tumor associated with titan cranioplasty was performed. The postoperative course was uneventful. Three months after surgery the patient no longer reported headache. The anatomical and pathological results concluded in intradiploic cavernous hemangioma. We discuss this case and others described in the literature.

In practice, the resected glioblastoma ratio is low. Of 952 glioblastomas treated in France in 2004, 56% were resected and 44% biopsied. An analysis of the literature confirms the importance of resection on survival. Perioperative drugs, surgical techniques, as well as intra- and postoperative imaging are analyzed in view of the literature.

Improvements in diagnostic tools such as CT scans and MRI, changes observed in histological classifications, and adjustments in neurosurgical practices have contributed substantially to this increase. Moreover, the aging of the population and the increasing occurrence of glioblastoma beyond 60 years of age are additional explanations. In Gironde (France), where a specialized registry has been established, the annual incidence of glioblastoma is 4.96/100,000. Wide geographic variations are observed, possibly linked to ethnicity.

These genetic diseases are suspected of being involved in approximately 1% of gliomas. Few data are available on glioblastomas and their characteristics among these diseases. Familial syndromes known to predispose individuals to glioblastoma are neurofibromatosis type 1, Li-Fraumeni's syndrome, tuberous sclerosis, and Turcot's syndrome. This review discusses glioblastomas related to these diseases and the current knowledge on the statistical, clinical, and molecular biology data.

Other molecular prognostic factors have been proposed, such as mutations of TP53 and PTEN, amplification of EGFR, and deletion of 10q, but their prognostic values remain controversial. MGMT promotor gene methylation is correlated with higher chemosensitivity and consequently is a good prognostic factor only in patients treated with chemotherapy.

Signs of bony regeneration are assessed in an attempt to understand the postoperative survival of trepanned patients.

They are highly malignant (grade IV). This group of tumors is morphologically heterogeneous. The WHO distinguishes between clinico-pathological entities, variants of entities and histological pattern. Variants are defined as being reliably indentified histologically and having some relevance for clinical outcome but as still being part of a previously defined overarching entity. Patterns of differentiation are identifiable by histological appearances but without clinical or pathological significance.

Their clinical presentation is often nonspecific, consisting of exophthalmos, diplopia, visual loss, orbital pain or signs of orbital inflammation. Imaging plays a major role in the etiological diagnosis, providing a precise analysis of the location of the lesion, its components, and its effects on adjacent and nearby structures. It studies tumor extension and often provides a good evaluation of its composition. Imaging is mainly performed with MRI. CT is needed when the lesion affects the orbital walls.

The endoscopic endonasal and transantral approaches offer a minimally invasive alternative to the classic transcranial or transconjunctival approaches to the medial aspect of the orbit. The medial wall of the orbit, the orbital apex, and the optic canal can be exposed through a middle meatal antrostomy, an anterior and posterior ethmoidectomy, and a sphenoidotomy. The inferomedial wall of the orbit can be also perfectly visualized through a sublabial antrostomy or an inferior meatal antrostomy. Several reports have described the use of an endoscopic approach for the resection or the biopsy of lesions located on ...

Hemangioma is a tumor that tends toward spontaneous regression. Lymphangioma is a malformation that tends to increase in size with growth spurts that can occur until adulthood. The treatment is decided according to the functional impact.

In childhood, the reduction of contents jeopardizes the size of the orbit. Reconstruction is always difficult, particularly after exenteration, and a well-made prosthesis is much better than a poor reconstruction.

The mean age at time of presentation is 60 years. The primary tumor is most often a carcinoma involving the breast (40%), lung (11%), or prostate (8%). Proptosis is the main clinical sign at diagnosis and is often associated with visual impairment, pain or ptosis. Imaging features are not specific; nevertheless, an enhanced extraconal tumor with osteolysis suggests the diagnosis. From a pathological point of view, there are no differences between the metastasis and the primary tumor. Regarding the average survival, the gold standard treatment remains radiotherapy.

The first symptoms appear in infancy and the involvement of the orbit and the face is present in nearly all children after the age of 5. The disease is unilateral in most cases but can exceptionally involve both sides of the face.

The course of these malignant tumors can be acute and can jeopardize the function of the eye or be life-threatening, especially in the event of metastatic locations. Extra-axial proptosis is by far the most frequent revealing symptom. Local and general examinations are of utmost importance.

Neurosurgical approaches consider the posterior two-thirds of the orbit and can be summed up as the superior, lateral, and superolateral approaches. Orbital rim removal enlarges the exposure when necessary. Each neurosurgical approach is described in this chapter. Schematically, subfrontal approaches are used to reach the inner quadrant orbital tumors and the others to access external quadrant tumors. Nevertheless, the choice of the approach is discussed regarding to the presumed pathologic preoperative diagnosis.

Primary tumors of the orbital walls are discussed in another section. Tumors from muscle and adipose tissue are rare or exceptional, except rhabdomyosarcoma, described in the section dedicated to pediatric tumors. Most frequent tumors are fibrous histiocytomas and solitary fibrous tumors, which often have a retrobulbar location. Fibrous histiocytoma is benign in only 65 % of cases. Fibrous solitary tumor is now better known (Ag CD34): this tumor is generally benign but frequently recurs.

Fourteen NPH patients (nine males and five females; mean age, 68 years) investigated by magnetic resonance imaging (MRI) before surgical diversion of CSF were retrospectively reviewed. Phase-contrast sequences were added to the morphological clinical protocol for quantification of CSF oscillations, which were recorded at the level of the cerebral aqueduct and the C2 and C3 subarachnoid spaces (SAS). The phase-contrast images were analysed with custom-designed dedicated flow segmentation software. The oscillations measured in this hydrocephalus population were compared to a previously studied healthy population. A difference of at least two standard deviations ...

Most of these papers contain a brief historical review of the work of the pioneers who contributed to operative modalities (Landolt et al., 1996; Liu et al., 2001; Walker, 1951; Welbourne, 1986). Several have been only experimental explorations on cadavers, used on a few patients, but were eventually abandoned, retaining only anecdotal value. In fact, open surgery currently uses the two classical approaches: intracranial and extracranial. The superior transcranial approach has retained two modalities: (1) subfrontal basal with or without resection of the orbital ridge and (2) subfrontal or subfrontotemporal.

The main goal of this technique is to fill the fractured vertebral body with PMMA cement to improve its stability. The efficiency of vertebroplasty on spinal pain related to osteoporotic fractures or the tumorous process has been widely described in the literature. However, the main problem of this percutaneous approach is the risk of cement leakage; to avoid this danger, balloon kyphoplasty was developed. There are two main goals of using balloons: first to reduce the deformity of the fractured vertebral body by inflation and then to fill the cavity created with cement injected without pressure. During the last 8 years kyphoplasty has bee...

Furthermore, although the RPG was identified on the MRI in more than two-thirds of the cases, more than half had adenohypophyseal failure: therefore, the visualization of a RPG does not mean that its functions are preserved. The involvement of the neurohypophysis is much rarer: one patient of 19 (5 %). The implications of the ischemic or compressive damage on the normal pituitary gland are discussed.

With no preoperative embolization, surgery was uneventful and the postoperative course was excellent. Based on the literature, we attempted to clarify the histogenesis of HB and to explain why they are exceptional in the supratentorial region in contrast to the posterior cranial fossa. The VHL gene is expressed particularly in Purkinje cells of the cerebellum, but this expression is also possible in supratentorial structures. Its mutation leads to developmental arrest of angioblasts that become potentially neoplastic cells. These CD133-positive pluripotent neoplastic angioblasts, similar to stem cells, may be immature HB in the brain. They als...

The relationship between a cervical bony abnormality is often unclear, and the investigations not always contributive. First-line treatment consists in physiotherapy. Surgery remains controversial, in both its indication as its modalities. However, well-adapted surgery gives a good result in 60-85% of cases.

A precise diagnosis is required for well-adapted and effective treatment, as is good knowledge of fibromatosis diseases. In some cases, the diagnosis of the nerve tumor will lead to a diagnosis of phakomatosis.

It transmits information between these neurons and their peripheral effectors in both directions (sensory receptors, skeletal muscles, and viscera). The afferences to the periphery correspond to the nerve motor content, whereas efferences from the periphery, in charge of delivering information to the central integrators, correspond to nerve-sensitive content. This information support depends on the intrinsic properties of the nerve itself. Peripheral nerve injuries are frequent and generate significant deficits.

These injuries can be detected using speed motor conduction and sensitivity conduction. The corresponding abnormalities are localized conduction abnormalities, presenting as deceleration or as a conductive block. Segmentary deceleration is perfectly well observed, such as in cases of carpal tunnel syndrome. The detection examination, recording motor unit potentials, can distinguish between a peripheral injury and a central injury as well as between a neurogenic injury and a myogenous injury. The precise study of the sensitivity potentials makes it possible to distinguish between a radicular injury, in which the sensitivity potentials are normal, and a plexus injury, in which the sensitivity pote...

This chapter describes the most common forms: the schwannomas and the neurofibromas. Schwannomas have two possible patterns of cells: Antoni A and B types. Neurofibromas are most often associated with neurofibromatosis NF(1) and may be localized, diffuse, or plexiform. The benign tumor structures account for the fact that they can be removed with or without preserving the concerned nerve. Malignant tumors (malignant peripheral sheath tumors) come from degeneration of neurofibromas in two out of three cases and have a poor prognosis.

Immediate mortality is still high but appears correlated to associated lesions. Today's treatments must preserve autonomy for these patients. For elderly patients, the treatment must be chosen in relation to the fracture analysis. In our opinion, surgical management is the treatment of choice for unstable fractures (type II). Conservative management is indicated for stable fractures.

Its radiologic features are not specific and are better recognized on MRI with a mass of a variable signal related to the percentage of caseous necrosis. A frequently associated thickening of the pituitary stalk suggests tuberculosis, requiring the search for another tuberculosis location.

Immunohistochemical studies are necessary for the histopathological diagnosis. The treatment of choice is surgical. To guarantee good progression, complete ablation is necessary. The clinical progression, radiological aspects, treatment, histopathology, and postoperative progression will be discussed.

The intraorbital location is relatively rare. The authors report a case of a 12-year-old male with an intraorbital dermoid cyst revealed by progressive right proptosis. The imaging aspects (CT scan and MRI) were consistent with intraconic dermoid cyst. The tumor was extirpated via a subfrontal approach. Histopathologic examination confirmed the diagnosis of dermoid cyst. The authors discuss the clinical symptoms, radiological aspects, and management.
