Unilateral hydrocephalus: atypical presentation of intracranial tuberculoma.

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.

Intraoperative ventriculo-stomographic evaluation of endoscopic cerebrospinal fluid diversion and flow restoration procedures.

Purpose: This prospective study was designed for intra-operative demonstration of cerebrospinal fluid (CSF) flow in ventricles and cisternal spaces before and after neuroendoscopic procedure. The aim of this study was to evaluate site of obstruction of CSF flow and subsequent stomal or aqueductal patency after endoscopic third ventriculostomy (ETV) or aqueductoplasty in patients with hydrocephalus of diverse aetiology.

Method: Seventeen patients with hydrocephalus due to diverse aetiology underwent ETV (n = 15) and aqueductoplasty (n = 2) or cysto-ventrticulostomy (n = 1) or transaqueductal removal of neurocysticercus cyst (NCC) (n = 1).

Central pontine myelinolysis in a pediatric head injury patient.

Central pontine myelinolysis occurs inconsistently as a complication of severe and prolonged hyponatremia, particularly when corrected too rapidly. It is a concentrated, frequently symmetric, noninflammatory demyelination within the central basis pontis. We describe a head injury patient who suffered this clinical entity as a consequence of rapidly corrected hyponatremia.

High pharyngoesophageal strictures after laryngopharyngectomy can also be treated by self-expandable plastic stents.

Background: Permanent dysphagia occurring after laryngectomy or laryngopharyngectomy can usually be treated by periodic dilation. Occasionally, however, conservative treatment is insufficient, and patients require long-term tube feeding. We describe 4 cases with stricture after laryngopharyngectomy who underwent insertion of self-expandable plastic stents (SEPSs) across the stricture for treatment of dysphagia.
