Multiple fractures involving the orbit and incidental finding of large fourth ventricular epidermoid

Epidermoid tumors located in the fourth ventricle are exceedingly rare, and the patients usually present with headaches, vertigo, and/or disequilibrium. We discuss the management of orbital floor and lateral wall fracture in a patient who was also incidentally diagnosed to have a large fourth ventricular epidermoid cyst. Although because of their availability and ease of use many allografts have been described, when available, the use of similar membranous bone of equivalent thickness makes the bone graft ideally suited for reconstruction of the orbital floor.
