Optical-chiasmatic region epidermoid with a suprasellar and prepontina region cysticercosis.

ABSTRACT

The Authors report a case of epidermoid in the optical-chiasmatic region associated with a cysticercosis in the suprasellar and prepontal region. The patient was surgically treated with success a bilobate cystic formation with ramifications adherent to the carotid siphon was found in front of optic nerves. Opening the arachnoid between the left optic nerve and carotid, a dysembriogenetic cystic formation was observed. Adherent to it there was the wall of a second parasitic cystic formation (probably cysticercosis) from which some small cysts slid away. After a review of the literature the Authors point out both the casual association of the two pathologies and the utility of C.T. scan in the diagnostic process of the above mentioned lesions.
