CT evaluation of orbital osseous hemangioma.

Two patients with osseous hemangioma of the orbit, and with typical features on plain radiography and computed tomography, are reported. The typical features of osseous hemangioma of the orbit on computerised tomography (CT) are: expansile bony lesion limited by a thin sclerotic rim, bony trabeculae radiating from the centre to the periphery of the lesion, and absence of an associated extra-tumoral soft tissue mass. To the best of our knowledge this is the first report of osseous hemangioma of the orbit evaluated by CT.
