title: Mucocele of the ethmoid sinus.
abstract: A 15-year-old female was evaluated for pain in the region of the right medial canthus and increasing exophthalmos. She had been diagnosed as having pseudo-tumor of the right orbit when she was 8 years old. The diagnosis was sustained until a second ophthalmologist requested a CT scan which demonstrated a mucocele of the right ethmoid sinus. Intranasal endoscopy revealed medial bulging of the right middle turbinate and meatus. Following a right external ethmoidectomy the eye returned to its normal position and pain disappeared. She has been asymptomatic for the past 4 years.
