Primary intraosseous cavernous hemangiomas of the orbit are rare tumors and the preoperative diagnosis is sometimes difficult. We report a case of an intraosseous cavernous hemangioma of the superolateral orbital rim, and the characteristic appearance on CT and MRI is described. A 61-year-old woman presented with a painless tumor on the frontal bone involving the right superolateral orbital rim. Bone window CT demonstrated a 2.5cm expansile, rounded, and well-marginated bony lesion with internal radiating trabeculations, forming a so-called sunburst pattern. The lesion was removed en bloc by the frontolateral approach. A brief epidemiological and radiological review of the literature is presented.
