ABSTRACT
Cavernous hemangioma of orbit is a benign, noninfiltrative, slowly progressive vascular neoplasm. It is usually asymptomatic but patients may present with proptosis and diminished vision due to compression of second cranial nerve, optic nerve. This can be usually diagnosed with the help of clinical examination and computed tomography (CT) or magnetic resonance imaging (MRI). Small sized tumours are worth wait and watch while large ones need surgical excision. In our case report, A 65-year-old male patient presented to the head and neck surgery with proptosis of left eye since 5 years along with decreased vision since 4 years. MDCT scan (orbits plain) suggestive of large solid retroocular, intraconal mass in left orbit leading to proptosis of left eyeball. The patient underwent excision of tumour through a transnasal endoscopic approach. Histopathological examination of the tumour identified as cavernous hemangioma. It is safe and effective way to access and excise the orbital tumours through the transnasal endoscopic approach. It is essential to have experienced surgeon in endoscopic procedures. The patient had satisfactory results at three months follow up and showed no symptoms or relapse on CT scans of orbital region.
