A previously healthy, 77-year-old man was admitted to the Instituto Nacional de Neurología y Neurocirugía reporting 4 months of increasing headache. Hydrocephalus and vesicular cysticerci in the subarachnoid space were diagnosed. A cerebrospinal fluid shunt was placed, and albendazole plus corticosteroids were administered. The patient did not attend follow-up appointments and returned 2 years later with hydrocephalus and subarachnoid parasites. A new cerebrospinal fluid shunt was placed and he received a second cycle of albendazole plus corticosteroids. Clinical improvement was observed; however, 6 months later magnetic resonance imaging showed new parasites now localized in the ventricular system (Figure, A). A third cycle of albendazole plus corticosteroids was administered. Magnetic resonance imaging performed 6 months later showed persistence of ventricular parasites (Figure, B). Neuroendoscopic surgery was planned but since the patient had difficulties getting to the hospital, the surgery was performed 8 months later. Magnetic resonance imaging performed just before the surgery showed an increase in the ventricular parasite burden (Figure, C and D). More than 40 parasites were removed and a new cycle of albendazole plus corticosteroids was then administered. There was no clinical improvement and the patient died 1 month later.
