Cysticercosis in the posterior cranial fossa.

ABSTRACT

Two cases of neurocysticercosis from Maharaj Nakorn Chiang Mai Hospital were reported with autopsy and surgical findings. The autopsy case was a 14-year-old girl who had a single cyst at the cisterna ambiens of the pineal region, causing hydrocephalus and severe brain edema accompanied with increased intracranial pressure and psychiatric problems but no definite localizing signs. The surgical case was a 35-year-old man with symptoms of increased intracranial pressure, localizing signs of ataxia of the left lower extremity and hearing loss in the right ear. Computed brain tomography showed a posterior fossa cyst with obstructive hydrocephalus. The cyst and the tissues from CP angle region were removed and sent to the Department of Pathology. Histopathologic appearance of both cases showed cysticercosis.
