Retro-orbital Hematoma and Proptosis Associated With Chronic Sinus Disease

Abstract
• Sudden unilateral proptosis occurred in a patient with a history of chronic sinusitis. The radiologic description of chronic sinusitis associated with the computerized tomography scan picture of a retro-orbital mass justified surgical exploration and evacuation of a hematoma. The proximity of the orbital cavity and the sinuses, plus their common venous drainage system, can account for this disease. (Arch Otolaryngol 106:442-443, 1980)
