• Proptosis of the left eye developed in a 51-year-old man with a long history of nasal polyposis. Displacement of the orbit was associated with a palpable mass superior and lateral to the orbit. Roentgenographic studies, including a sinus series, computed tomographic scan, and axial tomogram of the left orbit, showed a soft-tissue mass in the superolateral compartment of the left orbit and left frontal sinus, suggesting a mucocele. The surgical and pathological findings disclosed polyps of the frontal sinus invading the orbit through a dehiscence of the lateral orbital roof. To our knowledge, this is the first reported case of invasion of frontal sinus polyp into the orbit through the superolateral wall.
