A prospective cohort study to assess the frequency and risk factors for calcification in single lesion parenchymal neurocysticercosis

Neurocysticercosis (NCC) is the most frequent helminthic infection of the nervous system. It occurs when humans become intermediate hosts in the life cycle of the pork tapeworm Taenia solium after ingesting its eggs. The disease is transmitted from tapeworm carriers to healthy individuals through unhygienic food handling or by direct contact with human faeces [1]. NCC is the most common acquired cause of epilepsy in developing countries [2–4]. Classically, neurocysticercosis evolves through four stages: vesicular, colloidal, granular nodular and calcified [5,6].
