A Rare Case of Adenoid Cystic Carcinoma of the Sphenoid Sinus Presenting with Lateral Rectus Palsy.

A rare case of adenoid cystic carcinoma arising from the sphenoid sinus causing lateral rectus palsy is presented here. Adenoid cystic carcinoma of the paranasal sinuses is an aggressive neoplasm which needs early diagnosis and treatment. Ideal treatment paradigm for paranasal sinus tumors is yet to be established. A combination of surgery and radiotherapy offers a better disease control and survival.
