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)
A 43-year-old male presented with 3-month history of low-grade fever and headache. Radiological investigations revealed unilateral hydrocephalus. Unilateral obstruction of the foramen of Monro due to chronic tubercular ependymal inflammation was suspected and endoscopic septostomy was planned. Though ventriculo-peritoneal shunt is a simple method to treat… (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)

OBJECT Endoscopic third ventriculostomy (ETV) is increasingly being used as an alternative treatment for post-tuberculous meningitis (TBM) hydrocephalus. The aim of this study was to affirm the role of ETV in patients with TBM hydrocephalus and also to study the usefulness of cine phase-contrast MR imaging (cine MR imaging) for functional assessment of the… (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.
