Intraosseous Cavernous Hemangioma of the Frontal Bone -Case Report-

Abstract

A 32-year-old man presented with a primary intraosseous cavernous hemangioma manifesting as a small painless swelling of the right forehead. Radiography revealed a radiolucent osteolytic lesion in the right frontal region. Bone window computed tomography demonstrated a 1.5 cm mass between the outer and inner tables just lateral to the right frontal sinus. The outer and inner tables were thin and partially defective, but without bone fracture. Magnetic resonance imaging revealed a small mass lesion with bone erosion of the posterior table of the frontal bone. Preoperative examination yielded no final diagnosis. En bloc resection was performed. The histological diagnosis was primary intraosseous cavernous hemangioma. Total resection is recommended for definitive diagnosis of intraosseous tumor.
