RESUMO
A 38-year-old woman presented with sudden-onset painful lid swelling, proptosis and external ophthalmoplegia on the right side for 20 days, associated with loss of vision for nine days. On contrast-enhanced computed tomography (CECT), a retrobulbar mass was noted involving intraconal and extraconal spaces, extending up to the orbital foramina with enhancement and thickening of meninges. CT arteriography further revealed multiple feeding vessels from the maxillary artery. Embolization of feeding vessels followed by right orbital exenteration with primary reconstruction using forehead flap was done. This is an unusual case of orbital cavernous hemangioma (OCH) which emphasizes the importance of CT arteriography in specific cases of OCH, where routine neuroimaging may be inconclusive.
