LOPES, Pedro Garcia. Surgical treatment of cysticercosis in posterior cranial fossa. Arq. Neuro-Psiquiatr. [online]. 1971, vol.29, n.1, pp.76-92. ISSN 0004-282X.

Cysticercosis is one of the most severe parasitic diseases of the nervous system. When located in the posterior fossa, it presents a dramatic picture of intracranial hypertension. Seventy patients of cysticercosis in posterior cranial fossa have been studied, all of them attended at the Neurosurgery Service of the University of São Paulo Medical School, from 1945 to 1968. Owing to the great differences in surgical procedures, it has been the objective of this work to study the results according to the technique employed. The palliative surgeries that deviate the flow of the cerebrospinal fluid to extracranial regions were the kind of surgery that gave a better rate of recovery, demanded less re-operations and caused not only a less amount of trouble, but also of pos-operative deaths. Neurocysticercosis is usually a spreading process, parasites being found in several regions of the brain. So, intracranial shunts cannot be justified, unless, sometimes, for the direct removal of the parasite. The cases studied allow us to state that extracranial shunts, by their simplicity and effectivenss are at present the most convenient surgical procedure in the treatment of cysticercosis of the posterior cranial fossa.
