A Case of Sellar/Suprasellar Neurocysticercosis Mimicking a Craniopharyngioma.

Neurocysticercosis (NCC) commonly presents with seizures in developing countries such as Nepal. It may also present with raised intracranial pressure due to obstructive hydrocephalus when cyst is located in the fourth ventricle or foramen of Monro. There are four main stages of NCC (1) Vesicular, (2) Colloidal vesicular, (3) Granular nodular, and (4) Nodular calcified. The colloidal vesicular stages can cause arachnoiditis and thus can cause hydrocephalus whereas obstructive hydrocephalus is usually caused by racemose type of NCC. This case was a suprasellar cyst mimicking craniopharyngioma, supported with clinical history of poor visual acuity, endocrine abnormality, suggested radiological findings by computed tomography scan, and magnetic resonance imaging. Suprasellar NCC was confirmed only by intraoperative findings and histopathology report.
