Posttraumatic Cavernous Hemangioma of the Skull

AbstractA 59-year-old man presented with a slowly enlarging mass in the lateral orbital rim of the left eye for 1 year. He also reported a history of crania defect in the left front bone (6 years earlier) which was confirmed on the former computed tomographic (CT) scan. On examination, the solid mass lesion located in the left frontal extends to the lateral orbital rim of the left eye. CT scan showed a mass with poorly defined margins, which invaded the neighboring tissue and nearly damaged the bone, and located on the exact site of the preceding crania defect. Complete resection was performed, and the clinical diagnosis of cavernous hemangioma was confirmed on histopathologic examination.Skull cavernous hemangiomas are rare tumors for which the origin is not yet clear. We report a case in which the intraosseous hemangiomas developed at the same site of the preceding crania defect.
