BACKGROUND: Primary diffuse leptomeningeal primitive neuroectodermal tumor (PDL PNET) is extremely rare, with only 19 cases reported in the literature to date. We present a case of a child with rapidly progressive PDL PNET and a literature review. A 10-year-old boy presented with mood lability, hallucinations, generalized pain, enuresis, and headaches. Initial investigation failed to produce a diagnosis. The symptoms progressed to seizure, back pain, and papilledema. Imaging showed acute hydrocephalus and mild diffuse leptomeningeal enhancement without an identifiable primary lesion...

We report the case of a 41-year-old female with neurofibromatosis Type 1 (NF1) who developed a rosette-forming glioneuronal tumor (RGNT) in the tectal plate. This tumor was diagnosed in 2002 when the patient presented with obstructive hydrocephalus, which was subsequently treated with a ventriculoperitoneal shunt and then an endoscopic third ventriculostomy. Initially thought to be a pilocytic astrocytoma, it was followed with serial magnetic resonance imaging (MRI) until tumor progression and development of a large fourth ventricular cystic component prompted resection via suboccipital craniotomy...

Lateral meningocele syndrome (LMS) is a rare genetic connective tissue disorder. It is associated with morphological changes similar to those of other connective tissue disorders, with the unique distinction of multiple, often bilateral and large, lateral meningoceles herniating through the spinal foramina. In some cases, these lateral meningoceles can cause pain and discomfort due to their presence within retroperitoneal tissues or cause direct compression of the spinal nerve root exiting the foramen; in some cases compression may also involve motor weakness...

OBJECTIVE Ventriculostomy entry sites are commonly selected by freehand estimation of Kocher's point or approximations from skull landmarks and a trajectory toward the ipsilateral frontal horn of the lateral ventricles. A recognized ventriculostomy complication is intracranial hemorrhage from cortical vessel damage; reported rates range from 1% to 41%. In this report, the authors assess hemorrhagic risk by simulating traditional ventriculostomy trajectories and using CT angiography (CTA) with venography (CTV) data to identify potential complications, specifically from cortical draining veins...

Sirawat Srichatrapimuk, Somnuek Sungkanuparph
Cryptococcosis has been one of the most common opportunistic infections and causes of mortality among HIV-infected patients, especially in resource-limited countries. Cryptococcal meningitis is the most common form of cryptococcosis. Laboratory diagnosis of cryptococcosis includes direct microscopic examination, isolation of Cryptococcus from a clinical specimen, and detection of cryptococcal antigen. Without appropriate treatment, cryptococcosis is fatal. Early diagnosis and treatment is the key to treatment success...

Slit ventricle syndrome (SVS) is a well-known chronic complication of ventriculoperitoneal shunt (VPS) placement. In this report, we describe a unique anatomical change that we observed on the magnetic resonance (MR) images of the brain acquired from a patient with SVS. The patient was a 40-year-old woman who had undergone VPS placement at 3 months of age. A computed tomography scan of her brain revealed a slit-like ventricle. In addition, an MR image of her brain revealed upward ballooning of the third ventricle floor, which returned to normal after a lumbar puncture...

AIM: Shunt-dependent hydrocephalus (SDH) is a relatively common complication following aneurysmal subarachnoid hemorrhage (aSAH). Delay in diagnosis and treatment may worsen neurological outcome. This study was conducted to identify early clinical factors associated with SDH following aSAH. MATERIAL AND METHODS: Patients diagnosed with aSAH at our hospital from January 2010 through July 2014 were included. Patients aged ≤ 18 or ≥ 90 year, with concurrent arteriovenous malformation, treated with both clipping and coiling, or not receiving definitive treatment were excluded...

PURPOSE: We test the hypothesis that ventriculoperitoneal (VP) shunt insertion significantly increases contralateral positional plagiocephaly. METHODS: We reviewed 339 children who had a VP shunt inserted at Birmingham Children's Hospital between 2006 and 2013, noting laterality of shunt insertion and frontal or occipital position. We ascertained the presence of post-operative positional plagiocephaly using the cranial vault asymmetry index. Multinomial logistic regression modelling was used to examine relationships between plagiocephaly, shunt position, gender and age...

OBJECTIVE: Arrested hydrocephalus is stable ventriculomegaly without evidence of neurologic deterioration or symptoms. Management of arrested hydrocephalus in asymptomatic adults is controversial, with little clinical data. This case highlights the potential for decompensation in adults with arrested hydrocephalus and reviews the literature regarding pathophysiology and management of this clinical entity. PATIENTS AND METHODS: A 39 year-old gentleman with arrested hydrocephalus incidentally found during work-up for new-onset seizure and managed conservatively for ten years presented with increasing headache, memory loss, gait instability and urinary and fecal incontinence...

BACKGROUND: Longstanding overt ventriculomegaly in adults (LOVA) is characterised by chronic hydrocephalus presumed to begin during infancy, but arresting before becoming clinically detectable. Later in life clinical features of hydrocephalus ensue, typically in the 5th or 6th decades. Only a relatively small number of LOVA case series have been published, and ambiguity remains regarding optimal management. This case series describes a series of patients with LOVA treated successfully at a single neurosurgical institution using endoscopic third ventriculostomy (ETV)...

BACKGROUND: This paper describes a case of 4th ventricular mass, whose management had to be modified due to a rare variation of the occipital sinus (OS). CLINICAL DESCRIPTION: 32 year-old female presented with persistent headache and nausea. MRI showed a 4th ventricular mass and hydrocephalus. Venous sinus anatomy appeared unusual, thus an MRV was performed. MRV revealed the OS as the main drainage pathway for the whole brain, providing the only drainage between the superior sagittal sinus and the jugular veins through the marginal sinus (MS)...
