Here we focus on modern ioUS to analyze its use for localisation, visualisation and resection control in intramedullary cavernous malformations (IMCM). A series of 35 consecutive intradural lesions were operated in our hospital in a time period of 24 months using modern ioUS with a high frequency 7–15 MHz transducer and a true real time 3D transducer (both Phillips iU 22 ultrasound system). Six of those cases were treated with the admitting diagnosis of a deep IMCM (two cervical, four thoracic lesions). IoUS images were performed before and after the IMCM resection. Pre-operative and early postoperative MRI images were performed in all patients. In all six IMCM cases ...

We also carried out an updated review of the PXA-NF1 literature and found only eight previous reports of this clinical disease association. These reports have been limited to only certain regions of the world, with none yet reported from Africa, South America, Australia, and Eastern Europe. As far as we know, this might be the first such report from Africa. The case we present, in addition, demonstrated some other unique clinical, radiological, and histopathologic characteristics which have been highlighted in this review.

One patient had bilateral ischemic lesion resulting from perinatal hypoxia, one cavernoma, and two focal cortical dysplasias. All presented with motor or sensorimotor deficits and three had long-standing therapy refractory focal seizures. The extent of safe lesionectomy was determined using fMRI, fiber tracking, and PET studies and performed with intraoperative functional neuronavigation guidance and cortical stimulation. The achievement of the planned amount of resection was verified with an intraoperative MR examination. New persisting neurological deficits after surgery were not registered. One patient had temporary worsening of the right hand...

Out of 231 patients operated for cranial base meningiomas at the Karolinska University Hospital during 7 years, 25 complained of de novo trigeminal symptoms at clinical follow-up 3 months after surgery. Six were later lost to follow-up leaving 19 participants in the study, which was conducted using a questionnaire and a structured telephone interview. All patients complained of facial numbness, affecting the V1 branch in 10/19 patients (53%), the V2 branch in 18/19 (95%) and the V3 branch in 9/19 (47%). Surprisingly, only three (16%) suffered from trigeminal pain, which could be adequately managed by pharmacoth...

We have evaluated whether neuronavigation based purely on 3D ultrasound without any preoperative navigational imaging can provide necessary information for navigation and resection control. This application is a new way of utilizing ultrasound-guided neuronavigation. Eighteen patients were operated on with ultrasound-based navigation only; they represented 16% of all the 131 navigation-assisted procedures during our 1-year study period. Of the procedures, 2 were planned as diagnostic biopsies, 1 was resection of...

Humans are hardwired to enjoy food, and our bodies voraciously extract and store energy from food as if each meal was the last. As an amalgam of behavioral and metabolic disturbance, obesity is an attractive target for deep brain stimulation (DBS) since neuromodulation may be able to influence both eating behavior and metabolism. The current pandemic proportions of obesity combined with the failures and morbidity of modern treatments remain the impetus behind the application of DBS to this complex disease. We review the rationale and scientific foundations for obesity DBS and explain how this preclinical evidence has helped sculpt the design of the first human pilo...

A number of 138 consecutive patients were included in the analysis; all patients underwent high-resolution computed tomography (CT) scanning at time of admission with β2-transferrin testing used to confirm CSF leakage. Patients with acute surgical indications were operated as emergent; leaks were repaired at the time of initial surgery in patients with intracranial pressure < 15 cm H2O. The remainder of the study population was managed conservatively including use of prophylactic antibiotics; lumbar drainage (LD) catheters were placed in those patients with leakage persisting beyond 48 h.

In the present study, we examined the in vitro endurance of clip twisting to assess clip scissoring. To evaluate the clip-scissoring effect, we measured torque at the rotating aneurysm clip head (Sugita and Yasargil clips) using our own manufactured product. A silicon sheet 1 mm thick was clipped at several depths (3, 6, and 9 mm), and the clip head was mechanically rotated. Straight and fenestrated clips of titanium alloy were used in the present study. Cobalt alloy straight clips were also examined. Preliminary experiments indicated that torque values during cli...

In the literature, about 40 cases have been reported. However, due to the rarity of this pathology, there are no guidelines for diagnosis and treatment. Conservative, surgical, and endovascular concepts have been proposed. In order to work out an algorithm, we performed a systematic review of the literature and a retrospective analysis of patients, which have been treated in our institutions over the last decade. The clinical series was comprised of five patients. The symptoms ranged from transient vertigo to posterior circulation stroke. Diagnosis was established by dynam...

The outcome may be influenced by various technical nuances; therefore, treatment should be preferably done in specialized clinical centers with sufficient expertise in the management of this disorder.

In the last decades, many approaches have been introduced. Our strategy for the treatment of such tumors having large supratentorial extension with encasement of the internal carotid artery or compression of optic and oculomotor nerves has evolved in the attempt to improve the outcome. Currently, we favor a surgical technique consisting of two steps. As first step, we perform a retrosigmoid suprameatal approach in order to resect the posterior part of the tumor and obtain brainstem decompression. In the second step, carried out after patient’s recovery from the first surgery, we remove the supratentorial portion of the lesion using a frontotemporal craniotomy to achieve the ...

Gamma Knife and linear accelerator based systems using rigid frames preceded the development of frameless devices. The present report describes the development of microbeam radiosurgery, a technique which uses submillimetric beams of radiation to treat disease. Typically, the technique is employed using parallel arrays of beams delivered via a high-fluence synchrotron source. Beam widths between 20 and 950 μm have been used with the majority of studies utilizing beam widths less than 100 μm. In addition to its high precision, the technique allows users to take advantage of two unique properties of microbeams. The first is a remarkable tolerance of healthy ...

Our series includes 20 women and eight men. Of their 30 aneurysms, 24 were ruptured, and six were unruptured; there were 27 saccular and two fusiform aneurysms; one was dissecting. Their location was at the anterior-medullary (n = 4), lateral-medullary (n = 9), tonsillomedullary (n = 7), telovelotonsillar (n = 6), and cortical (n = 4) segment of the PICA. In 18 patients, angiographic features suggested hemodynamic stress including an absent contralateral PICA or ipsilateral anterior inferior cerebellar artery, termination of the vertebral artery (VA) at the PICA, and hyperplasia or occlus...

Surgical resection is curative when complete removal of benign meningiomas is contemplated. Incompletely excised and recurrent tumors are frequently treated with fractionated radiation therapy or stereotactic radiosurgery. The purpose of this study is to evaluate the short-term radiological and functional outcomes of a single center using linear accelerator (Linac) stereotactic radiosurgery for the treatment of intracranial meningiomas. Twenty-nine patients (12 males and 17 females) with 30 meningiomas, in different brain locations (skull base and non-skull base meningiomas), were treated with Linac-based stereotactic radiosurgery. The mean tumor volume was 6.3 cm3, and the mean tumor marginal a...

The authors report a case with this tumor and discuss its clinical and radiographic characteristics. A 36-year-old man presented with 6-month history of diplopia. Right abducens nerve paresis was noted on neurologic examination. Magnetic resonance imaging revealed a 4-cm sized heterogeneously enhancing mass in the right cerebellopontine angle. Although schwannoma was suggested, no direct radiographic evidences regarding its origin were identified. Instead, the facial and vestibulocochlear nerve complex was found to be displaced posteriorly by the tumor on MR three-dimensional T2-weighted driven equilibrium sequence. Resection of the tumor was carried out via retrosigmoid approach. As the encapsulated partially ...

During the study period, 1,013 patients underwent surgery for spinal cord tumors. Fifty-two of the patients had a myxopapillary ependymoma. Forty-eight of these patients underwent surgery at our institutions. There were four patients who came for consultations only. Fourteen pediatric patients were diagnosed with myxopapillary ependymoma. The overall average age at which a patient was diagnosed was 31.8 years. The average age a child was diagnosed was 12.6 years. The adult mean age was 38.7 years. The clinical presentation was of a slow, indolent course, with average symptom duration of 20.8 months. Overall, the pediatri...

Low scores according to Glasgow Coma Scale are also considered as serious poor prognostic factor. The aims of the study were to investigate whether there is a correlation between the two measurements in patients with traumatic brain injury and whether serum neuron-specific enolase levels have potential as a screening test to predict outcome. A total of 169 consecutive patients with traumatic brain injury admitted to our clinic between 2002 and 2005 are included in this study. Those patients, who had any major health problem before trauma, were excluded from the study. However, patients with isolated head injury were included in the study.

Together with a caudal end of the primitive internal artery, trigeminal, otic, and proatlantal intersegmental arteries, it represents the remnant of vascular channels’ unsuccessful involution which function normally stops in human embryo with 12 to 14 mm crown–rump length. The persistence of hypoglossal artery alone is usually incidental and asymptomatic finding during the routine angiography, while during autopsies or surgical operations, its presence is frequently associated with other vascular or organic abnormalities and diseases. The aim of this review is to document the hypoglossal artery developmental morphology, as well as the normal anatomical and clinical ...

The diagnostic value of single-photon emission computed tomography (SPECT) for postoperative hyperperfusion in moyamoya patients is well established, but that of magnetic resonance (MR) imaging/angiography is undetermined. A 22-year-old woman with hemorrhagic-onset moyamoya disease underwent STA–MCA anastomosis on the right hemisphere, but she suffered from transient left hemiparesis and facial paresis owing to cerebral hyperperfusion from 3 to 11 days after surgery as delineated by SPECT. The time-sequential 3-T MR angiography revea...

The 5-year survival rates vary from 40% to 70% depending on clinical prognostic criteria, and many of the patients who survive exhibit long-term neurocognitive and/or neuroendocrine sequelae. Because of these results, research is required to increase our understanding of the basic biology of medulloblastoma, helping to refine patient stratification, decrease side effects of treatments, identify novel prognostic markers, and discover new less toxic therapies. The recognition that some medulloblastomas occur in familial cancer syndromes has led to some important discoveries in the molecular pathogenesis of medulloblastoma. These syndromes provide us with clues regarding alterations...

The target was based on magnetic resonance (MR) images merged with computed tomography scan images taken on the day of surgery while patient was on a stereotactic frame. In order to reveal structures not discernible in MR images, the Schaltenbrand digital brain atlas was merged onto the patient’s images. Target and trajectory of the depth electrode were chosen based on three-dimensional imaging reconstructions. A surgical plan was devised to disconnect the hypothalamic hamartoma from the hypothalamus, medial forebrain bundle, fasciculus princeps, and dorsal longitudinal fasciculus. Our target...

Only five cases of intracranial aneurysm formation and/or subarachnoidal hemorrhage associated with brucellosis have been reported. In this paper, we take the opportunity to review these reports and present a new case of basilar artery aneurysm and subarachnoidal hemorrhage due to brucellosis.

The cooperation between ENTs and neurosurgeons has recently pushed the use of such approach also in the removal of some intradural lesions, which has promoted the interest for an anatomic study to identify the anatomical landmarks and the dangerous points during the endoscopic approach to this area. In six fresh cadaver heads, unilateral and bilateral measurements between the main landmarks of the approach were performed by means of an endoscopic endonasal approach. A wide exposure of the midline anterior skull base was realized. The maximum of lateral extension was obtained between the two medial orbital ...
