The authors report a case of a female patient, age 22, who presented episodes of focal seizures, right hemiparesis and dysphasia of five months duration. The neurologic exam revealed bilateral papilledema and computarized tomography of the head showed a cystic lesion (70x77 mm) in the left fronto-temporo-parietal area, midline shift and similar lesions scattered in the brain parenchyma. She was submitted to a left craniotomy with the diagnosis of cerebral cysticercosis and the major cyst (Cysticercus racemosus) and a small cortical cyst (10x10 mm) were removed to aliviate the increased intracraneal pressure and for histopathological examination. Thirteen days after surgery she was discharged without neurological deficits, except mild papilledema. One month later she was treated with praziquantel (50 mg/kg/day) during 21 days. The CSF examination was normal before the treatment started and showed a transient eosinophilic cellular reaction with positivation of the complement fixation test for cysticercosis while on treatment. The CT-Scan performed before the medical treatment revealed ventricular dilatation and several low density areas (10 to 40 mm) scattered in the cerebral parenchyma, including the operative site. CT-Scan performed three months later showed small low density areas only in the left cerebral hemisphere, including the operative site, calcification in the parenchyma, and slight dilatation of the left lateral ventricle. The clinical evolution was uneventfull and the neurologic examination was normal three months later.
