BACKGROUND The objective of this study is to evaluate the sensitivity and specificity of DWI in differentiating brain abscesses from other intracranial cystic lesions. METHODS One hundred fifteen patients with 147 cystic lesions (mean age, 26.4 year) were prospectively studied with DWI on a 1.5-T magnetic resonance imaging. Lesions appearing hyperintense… (More)
OBJECTIVE This is the first report of the simultaneous combined use of trans-sphenoidal and trans-ventricular-endoscopic route for decompression of a giant pituitary adenoma. METHOD A 38 year old man presented to us with symptoms of raised intracranial pressure along with visual and hypothalamic disturbances. The CT scan revealed destruction of the sella… (More)
OBJECTIVE Various approaches including endoscopy have been used for the treatment of intraventricular and cisternal NCC. We present our technique of Neuro-endoscopic management of intraventricular NCC. METHODS Twenty-one cases, 13 females and 8 males (age range 12-50 years; mean, 25.7 years), of intraventricular NCC [lateral (n = 6), third (n = 6), fourth… (More)
OBJECTIVE Fourth ventricular neurocysticercosis (FVNCC) usually presents with obstructive hydrocephalus. Available treatment options are medical, external cerebrospinal fluid diversion, microsurgical, or endoscopic removal alone or in combination. We present our experience of transaqueductal removal of FVNCC by angiographic catheter with endoscopic third… (More)
Paragangliomas are tumors arising from extra-adrenal paraganglia and account for 0.3% of all neoplasms. The carotid body and temporal bone are the most frequent sites of paraganglioma, though it has been reported to occur in almost every part of the body. Spinal paragangliomas are uncommon and mainly take the form of intradural compression of the cauda… (More)

The role of neuroendoscopy in patients of tuberculous meningitis with hydrocephalus (TBMH) is not yet established. We present details of endoscopic morphology, and analyze outcome of Neuroendoscopy performed in 28 patients (15 males and 13 females, average age 23 years) of TBMH in last 2.5 years. Endoscopic procedures performed included endoscopic third… (More)
We describe an 18-month-old male child presenting with delayed milestones. MRI revealed absent lateral and third ventricles associated with fusion of the posterior cerebral hemispheres.
