IVth ventricular neurocysticercal cyst: A rare cause of acute hydrocephalus
An 11-year-old boy presented with acute-onset projectile vomiting, bifrontal headache, and altered sensorium. Contrast-enhanced MRI brain was suggestive of intraparenchymal and intraventricular neurocysticercosis, with an intraparenchymal ring-enhancing lesion with central scolex in the left cingulate gyrus and a large cyst enlarging the IVth ventricle, with obstructive hydrocephalus (figure).1 Intraventricular cysticerci with acute hydrocephalus are rare.1 In contrast to intraparenchymal cysts, intraventricular cysts are large and typically lack an identifiable scolex.2 Confirmation of cysticerci is based upon identificat...

Hydrocephalus and neurocysticercosis: cases illustrative of three distinct mechanisms.
CONCLUSIONS: NCC should be considered as a possible diagnosis for patients suffering from hydrocephalus when they originate from or have traveled in endemic areas, MRI of the spine is mandatory to search for intraspinal lesions.

Cervicomedullary neurocysticercosis causing obstructive hydrocephalus
We present a 45-year-old man with tussive headache and blurred vision found to have obstructive hydrocephalus from a neurocysticercal cyst at the cervicomedullary junction who underwent surgical removal of the cyst. We performed a suboccipital craniectomy to remove the cervicomedullary cyst en bloc. Cyst removal successfully treated the patient’s headaches without necessitating permanent cerebrospinal fluid diversion. Neurocysticercosis is the most common parasite infection of the central nervous system causing seizures and, less commonly, hydrocephalus. Intraventricular cysts or arachnoiditis usually cause hydrocephalus...

Intraventricular adult Taenia solium causing hydrocephalus: A case report.
Conclusion: The present case highlights the importance of maintaining high suspicion for NCC in all patients presenting with seizures or hydrocephalus of unknown cause. Even in patients with a very remote history of residence in an endemic country, NCC can be an overlooked, underlying cause of both chronic neurologic symptoms, as well as acute, life-threatening neurologic emergencies.

Research Articles Paenibacillus infection with frequent viral coinfection contributes to postinfectious hydrocephalus in Ugandan infants
Postinfectious hydrocephalus (PIH), which often follows neonatal sepsis, is the most common cause of pediatric hydrocephalus worldwide, yet the microbial pathogens underlying this disease remain to be elucidated. Characterization of the microbial agents causing PIH would enable a shift from surgical palliation of cerebrospinal fluid (CSF) accumulation to prevention of the disease. Here, we examined blood and CSF samples collected from 100 consecutive infant cases of PIH and control cases comprising infants with non-postinfectious hydrocephalus in Uganda. Genomic sequencing of samples was undertaken to test for bacterial, f...

Diagnostic Challenges of Acapsular Cryptococcus neoformans in an Immunocompetent Individual Manifesting as Chronic Hydrocephalus (P6.321)
CONCLUSIONS: Awareness of acapsular forms of C. neoformans is an important consideration in selecting diagnostic assays. Immunocompetent hosts with unique C. neoformans phenotypes may exhibit unconventional clinical courses making timely diagnosis challenging.Disclosure: Dr. Mahajan has nothing to disclose. Dr. Dharia has nothing to disclose. Dr. Sheehan has nothing to disclose.

Cystic lesion of the fourth ventricle: Role of CISS
A 13-year-old boy presented with headache of 1 month and vomiting for 10 days. Salient examination findings were left lateral rectus paresis and papilledema. A contrast-enhanced CT followed by MRI brain revealed an ill-defined fourth ventricular cyst with communicating hydrocephalus (figure 1). Subsequently, a constructive interference in steady state (CISS) sequence revealed a fourth ventricular cysticercus (figure 2).

Patterns of Hydrocephalus Caused by Congenital Toxoplasma gondii Infection Associate With Parasite Genetics
Four anatomical patterns of hydrocephalus secondary to congenital Toxoplasma gondii infection were identified and characterized for infants enrolled in the National Collaborative Chicago-based Congenital Toxoplasmosis Study. Analysis of parasite serotype revealed that different anatomical patterns associate with Type-II vs Not-Exclusively Type-II strains (NE-II) (P = .035).

Neurocysticercosis: An Uncommon Cause of Acute Supratentorial Hydrocephalus
We report a 29-year-old woman with acute supratentorial hydrocephalus due to intraventricular neurocysticercosis (NC). Aqueductal stenosis due to web formation and a free floating intraventricular cyst with scolex were pathognomonic and led to the diagnosis of NC. Worldwide, NC is the most important parasitic infection of the central nervous system but is very uncommon in non-endemic regions. Intraventricular abnormalities occur in approximately 30% of the patients. Magnetic resonance imaging (MRI) plays a crucial role in the diagnostic work-up and in guiding intervention.Teaching Point: Brain magnetic resonance imaging in...
