Treatment of Subarachnoid Neurocysticercosis with Cysts in the Basilar Cisterns or Sylvian Fissures
Subarachnoid neurocysticercosis (NCC) with cysts in the basilar cisterns or Sylvian fissures represents a severe presentation of central nervous system cysticercosis, requiring a structured, multi-component treatment approach.
Clinical scenario
When cysticercal cysts are located in the basal cisterns of the subarachnoid space or Sylvian fissures, manifestations can be severe. Hydrocephalus is an important complication that must be identified and managed as part of the overall treatment plan before antiparasitic therapy is initiated.
Treatment approach (partial overview)
Management follows a coordinated sequence: when hydrocephalus is present, surgical intervention is recommended before antiparasitic therapy begins. Anti-inflammatory therapy is initiated prior to antiparasitic treatment. Antiparasitic therapy is required and is typically prolonged. For patients who require extended anti-inflammatory courses, a steroid-sparing agent may be considered as part of the regimen.
The complete protocol — including specific agents, sequencing, and duration — is available via the link below.
Treatment goals
The goal is radiologic resolution of viable cysticerci on MRI and resolution of other evidence of cysticerci. Responses often require prolonged therapy, which can last for more than a year.

- We recommend that patients with subarachnoid cysts be treated with antiparasitic drugs (strong, low).
- We recommend anti-inflammatory therapy (such as high-dose corticosteroids) for subarachnoid NCC initiated prior to antiparasitic drugs (strong, moderate).
- We recommend that patients with hydrocephalus from subarachnoid NCC be treated with shunt surgery in addition to medical therapy (strong, low).
- We suggest that methotrexate be considered as a steroid-sparing agent in patients requiring prolonged courses of anti-inflammatory therapy (weak, low).
- Options to improve responses include prolonged administration of albendazole (15 mg/kg/d for months) or combination therapy with albendazole (15 mg/kg/d plus praziquantel 50 mg/kg/d).
- We suggest that antiparasitic therapy be continued until there is radiologic resolution of viable cysticerci on MRI and resolution of other evidence of cysticerci (weak, low).
