Organized Hematoma of the Sphenoid Sinus With Acute Blindness: Insight Into Pathogenesis of Disease

Sinonasal organized hematomas (OHs) are rare lesions that primarily localize to the maxillary sinus. The rate of growth of these masses has not been described in the literature. We present a case of a 59-year-old gentleman with polyostotic fibrous dysplasia who presented with acute loss of vision in the left eye from an expanding OH of the sphenoid sinusitis. After expanded endonasal, transpterygoid approach and debulking, patient experienced significant vision improvement. Close follow-up imaging preoperatively allowed radiologic documentation of the rate of OH growth and this is presented in detail.
