Objectives – To find out natural course of solitary cerebral cysticercosis (SCC) cases after treating them with 2 weeks albendazole therapy. Material and methods – All patients with SCC were treated with 2 weeks of albendazole therapy with follow‐up radiological scan at 6 months and 2 years. The evolution of lesion was noted as complete resolution, calcification or persistent active. Antiepileptic drugs (AED) prophylaxis was given for 1 year in patients with complete resolution and for 2 years in calcified lesion, respectively. AED was continued in persistent lesion group till it became calcified or resoluted completely. One‐year follow‐up was done in all after stopping AED. Results – Among 345 cases, 226 (65.5%) had complete resolution with very low seizure relapse rate with 1 year of seizure free period on AED treatment. On the contrary, 105 (30.5%) had calcified lesion with high seizure relapse rate after stopping AED treatment with 2 years of seizure free period. Fourteen patients (4%) could not stop their antiepileptic medication at all because of active lesion. Conclusion – Two‐third of patients with SCC have favorable outcome with complete resolution and needs short‐term AED prophylaxis and the rest one‐third requires long AED treatment to prevent seizures.
