Maffucci syndrome is an extremely rare disorder characterized by benign enchondromas, skeletal deformities, and cutaneous lesions composed of abnormal blood vessels. Enchondromas rarely arise in the cranial bones. Interdural pituitary transposition is an effective way to gain access to the posterior clinoid, without affecting the function of the pituitary gland. Here, the authors present a case of a posterior clinoid process enchondroma in a patient with Maffucci syndrome. The tumor was resected via an interdural pituitary transposition fashion. Four months postoperatively, the patient’s oculomotor function had recovered to normal and the function of the pituitary gland was preserved intact.
