Bilateral Orbital Cavernous Hemangioma

Cavernous hemangioma of the orbit (CHO) is a benign slow-growing lesion of intracanal space. Bilateral orbital cavernous hemangiomas are extremely rare, so that only a few cases have been reported in scientific literature. A 54-year-old patient presented a 1-year history of impaired visual acuity of the left eye. Physical examination showed a left axial propotosis. Orbital magnetic resonance imaging showed a 28 mm diameter intraconal space mass of the left orbit, as well as another 11 mm diameter lesion in the right eye, in the superomedial extraconal space. A superior wall left orbitotomy was performed with a total removal of the tumor. The right lesion was respected. Histopathological examination confirmed the diagnosis of CHO. Bilateral cavernous hemangiomas are extremely rare. Orbital imaging guides the diagnosis. The neurosurgeons prefer craniotomy while ophthalmologists favor various modifications of orbitotomies.
