Background: In patients affected by neurocysticercosis (NCC), the extraparenchymal location of the parasites generates the most severe form of the disease. Due to the difficulty in its diagnosis and management, there are still many questions; in particular, the natural history of parasites at this location is not well known.
Methods: We included 21 patients with vesicular extraparenchymal NCC who had not received treatment for at least 18 months.
