Magnetic resonance imaging of neurocysticercosis

Neurocysticercosis (NCC) is involvement of the central nervous system (CNS) by the porcine tapeworm, common in developing countries with poor sanitation. The disease has been noted increasingly in nonendemic areas because of travel and immigration from affected regions. The magnetic resonance (MR) appearance can be characteristic, with single or multiple cysts and varying degrees of wall enhancement and surrounding edema, depending on the stage of the life cycle of the larva and its associated cyst.
