Rare Intraosseous Cavernous Hemangioma of the Orbit

Abstract

A healthy 52-year-old man presented with a painless, enlarging, right lateral orbital nodule of 1-year duration (A, arrow). Clinical examination revealed a 2.3-cm firm immobile lateral orbital rim mass. Computed tomography displayed an expansile and osteolytic neoplasm of the zygoma with orbital and extraorbital extension (B). Lateral orbitotomy exposed a porous neoplasm of the anterior zygomatic face (C). The exophytic component was resected, and histopathological examination demonstrated multiple, dilated, blood-filled cavities between bony trabeculae, consistent with a benign intraosseous cavernous hemangioma (D). Orbital intraosseous cavernous hemangiomas are rare, and malignancy should be ruled out in the setting of a progressive osteolytic neoplasm (Magnified version of Figure A-D is available online at www.aaojournal.org/).
