Giant parenchymal cysticercosis with unusual imaging features.
Giant neurocysticercosis is a relatively rare condition. A 40-year-old woman presented with left focal seizures and progressive left hemiparesis. A CT scan of the brain showed multiple hypodense lesions in the right cerebral hemisphere with no contrast enhancement or perilesional edema. MRI showed multiple hypointense lesions in the right perisylvian area. At surgery, the lesion was found to be a single large parasitic cyst measuring approximately 5.0 x 4.5 x 5.0 cm and the same was excised. Histopathology showed a solitary cysticercus cyst with scolex. The patient made an uneventful recovery. This imaging appearance of giant neurocysticercosis is very unusual and only two similar instances have been reported thus far.
