Case report of cavernous haemangioma in the supraorbital region in the extraconal space: A rare location.

Abstract

Cavernous haemangioma is the most common benign non-infiltrative neoplasm of the orbit. Most cavernous haemangiomas are intraconal and lateral in location. We present a rare case of a cavernous haemangioma with an unusual location in the supraorbital region of the orbit, presenting with soft tissue swelling. Cavernous haemangiomas are the most common benign non-infiltrative neoplasms of the orbit and have a slowly progressive mass effect. A slowly progressive proptosis is the typical presenting symptom. Extraocular muscle impairment and impaired visual function are seen with large lesions and with lesions located at the orbital apex. Most cavernous haemangiomas are typically intraconal and lateral in location. Extraconal and medial locations are uncommon. Ultrasound, computed tomography and magnetic resonance imaging are useful imaging techniques for the evaluation of such tumours. Treatment of the tumour is surgical excision. Complete excision is generally accomplished as the tumour is well-encapsulated with relatively few feeding vessels.
