Calcified parenchymal neurocysticercosis (CPN) is a distinct, late-stage presentation of CNS cysticercosis in which the parasitic lesions have calcified into nodular deposits within the brain parenchyma and no viable cysts remain. This inactive form calls for a management strategy that differs from active infection.
Nodular calcifications are present in the brain parenchyma with no evidence of viable cysts. Despite the absence of active infection, patients may continue to experience symptoms — most notably seizures — attributable to the calcified lesions and the surrounding perilesional changes.
Evidence-based guidance addresses the role of symptomatic therapy in this calcified-lesion population and, in selected patients with refractory seizures, a specific surgical evaluation pathway — full details and the structured algorithm are in the complete protocol.

We recommend symptomatic therapy alone instead of antiparasitic drugs in patients with calcified parenchymal lesions (strong, moderate).
In patients with refractory epilepsy and CPN, we suggest evaluation for surgical removal of seizure foci (weak, low).
