    CYSTICERCOSIS OF THE CENTRAL NERVOUS-SYSTEM - CLINICAL AND THERAPEUTIC CONSIDERATIONS
    (1984) TORREALBA, G; DELVILLAR, S; TAGLE, P; ARRIAGADA, P; KASE, CS
    In a group of 40 cases of cysticercosis of the CNS, 59% presented with intracranial hypertension due to obstructive hydrocephalus. Ventricular or cisternal cysts, and chronic cysticercus meningitis were the most common causes of hydrocephalus. Seizures occurred in 40% of the patients, in one-half of them in association with CT-detected parenchymatous cysts. In 20% of the cases progressive mental deterioration was the main clinical feature, at times associated with hydrocephalus. CT scan provided the highest diagnostic yield, being abnormal in 90% of cases. Long term prognosis was poor, with a mortality rate of 38% over a 40-mo. follow-up period. The most common cause of death (60%) was meningitis. CSF shunting is the treatment of choice for hydrocephalus, irrespective of its mechanism. Surgical resection is indicated in some cases with a single superficial (cortical) or posterior fossa cyst. Supratentorial cysts carry a relatively benign prognosis.
