Primary intraosseous cavernous hemangioma of the zygoma: A case report and literature review

Intraosseous hemangiomas are rare. We report the case of a 47-year-old man who presented with a gradually enlarging left zygomatic mass that had caused pain, deformity, and superficial soft-tissue swelling. Computed tomography revealed a well-circumscribed 2.0 x 2.5-cm mass with a ground-glass matrix in the left zygoma. Following surgical excision, the patient's symptoms resolved. Findings on pathologic examination of the excised tissue were consistent with an intraosseous cavernous hemangioma. We describe the features of this rare case, we discuss the pertinent radiologic features and pathophysiology of intraosseous hemangiomas, and we review the available literature.


Intraosseous hemangiomas account for less than 1% of all tumors.1 Their most common sites are the calvaria and the vertebral column.1 Their presence in the midface, including the zygoma, has been described only in a few isolated case reports.2
