Intracranial hypertension: Most often it is due to obstruction of cerebrospinal fluid (CSF) circulation caused by basal or ventricular cysticercosis. It may be due to large cysts displacing midline structures, or the so-called "cysticercotic encephalitis" caused by the inflammatory response to a massive infestation of cerebral parenchyma with cysticerci (Cysticercosis larvae).
