DETECTION OF AN ABERRANT MOTILE LARVAL FORM IN THE BRAIN OF A PATIENTWITH NEUROCYSTICERCOSIS

Neurocysticercosis is the most common parasitic infection of the centr al nervous system in humans. The adult pork tape worm, Taenia solium, resides in the lumen of the intestine, and the only structural element of an adult worm usually found within a tissue cyst in the brain or i n muscle is a single invaginated scolex. We report a highly unusual, a nd perhaps unique, occurrence of neurocysticercosis in which an aberra nt worm-like larval form, 12.5 cm in length, was found within a cyst i n brain parenchyma.
