We describe a patient with an incidental finding of an expansile osteolytic
lesion centered in the sphenoid involving 3 cranial bones-frontal,
temporal, and sphenoid-and invading the brain parenchyma and orbit. Biopsy
demonstrated an epidermoid. The lesion was excised through frontotemporal
craniotomy. Despite the benign nature of the tumor, the epidermoid had a
destructive pattern of growth. Complete resection was needed to adequately
address the inflammatory mass effect of the large lesion.
