title: Subperiosteal orbital hemorrhage associated with chronic sinusitis: a case report and review of the literature.
abstract: A case of subperiosteal orbital hemorrhage associated with chronic sinusitis is reported. A 57-year-old woman had a sudden onset of severe orbital pain and exophthalmos in the left eye. Computed tomography revealed a discrete round mass in the left retro-orbital space. An external frontoethmoidectomy was performed to evacuate the hematoma of the subperiosteal space. Additionally, the mucosa was edematous in the left ethmoid sinus. It appears that subperiosteal orbital hemorrhage in this case was caused by rupture of vessels which were inflamed as a result of sinusitis. Orbital hemorrhage associated with chronic sinusitis has rarely been reported. Diagnosis and treatment are discussed and etiologic factors are reviewed.
