Neurocysticercosis
Key Points
Key Points
- Neurocysticercosis (NCC) is a spectrum of diseases that differ in pathogenesis and optimal management.
- Symptomatic therapya should be the focus of initial and emergency management.
- Anti-parasitic treatment is important, but never an emergency.
- Parenchymal cystic NCC has better outcomes if treated with anti-parasitic drugs along with corticosteroids.
- Subarachnoid NCC does not respond well to single anti-parasitic drugs at doses and durations used for parenchymal NCC. Optimal management may require chronic anti-inflammatory therapy, intensive anti-parasitic therapyb and surgical therapy.c
- Ventricular NCC of the 3rd and lateral ventricles should be treated with minimally invasive surgery when possible, but minimally invasive and open craniotomy are options for 4th ventricular disease. Open craniotomy or cerebrospinal fluid (dCSF) diversion along with anti-parasitic drugs are optimal in select cases. Anti-parasitic therapy should be deferred until after surgical therapy.
- Calcified lesions do not contain viable parasites and should not be treated with anti-parasitic drugs.
b Anti-parasitic therapy for subarachnoid NCC may include prolonged courses of albendazole, high dose albendazole, or combinations of praziquantel and albendazole.
c
Surgical therapy for subarachnoid NCC may include CSF diversion for hydrocephalus or minimally invasive surgical debulking.
d
Adherent cysticerci should be managed with CSF diversion along with anti-parasitic drugs. Open craniotomy is effective for 4th ventricular lesions and the choice of approaches should depend on local surgical expertise.
