|Description:||Under a low magnification of 100X, this photomicrograph of a brain tissue specimen revealed the presence of cysticerci in a case of cysticercosis, an infection due to the ingestion of eggs of a pork tapeworm, Taenia solium. Infestation of the brain tissue by larval tapeworms is known as neurocysticercosis.|
The symptoms of cysticercosis are caused by the development of cysticerci in various sites. Of greatest concern is cerebral cysticercosis (or neurocysticercosis), which can cause diverse manifestations including seizures, mental disturbances, focal neurologic deficits, and signs of space-occupying intracerebral lesions. Death can occur suddenly. Extracerebral cysticercosis can cause ocular, cardiac, or spinal lesions with associated symptoms. Asymptomatic subcutaneous nodules and calcified intramuscular nodules can be encountered.
