Cysticercosis in one of the most common parasitoses in the world but is rare in France. This is the case of a thirty two years old man who had a stroke which revealed a neurocysticercosis, the diagnosis of which appeared on CT-scan. MR-imaging gave a more precise topographical diagnosis of the cysticercosis lesions and allowed a physiopathological understanding of the stroke. The ischemic lesion in the lenticulostriate territory was due to cysts in the sylvian fissure at the level of the beginning of those arteries with a perilesional inflammatory reaction. We learned the link between cysticercosis and stroke studing the cases reported in the literature.
