title: A rare case of racemose neurocysticercosis and its complications. Case report.
abstract: Neurocysticercosis is a central nervous system infection caused by the pork tapeworm Taenia solium. The disease is endemic in Central and South America, Asia and Africa. Racemose neurocysticercosis refers to cysts in the subarachnoid space and is characterized by proliferative lobulated cysts without a scolex. We report a case of a 43-year-old woman with an eight-month history of headaches, ataxia and loss of vision. CT and MRI showed an intraventricular cyst, causing entrapment of Monro foramina and hydrocephalus, smaller cysts at subarachnoid space in temporal lobes, Sylvian fissures, supra-selar and perimesencephalic cisterns, and an intra-orbital cyst. Additionally, there were acute ischemic vascular lesions on the left thalamus and corpus callosum splenium and subacute ischemic lesions of both occipital lobes. The diagnosis of racemose cysticercosis was made after biopsy and drainage of the intraventricular cyst. It is important to recognize neurocysticercosis as a differential diagnosis in intra-cranial cysts, not only intraparenchymal cysts.
