Nontraumatic Subperiosteal Orbital Hematoma Associated with Ethmoid Sinusitis: A Case Report

ABSTRACT

Subperiosteal hematoma of the orbit is a rare disease and most of the cases occur in young adult males as a result of direct facial or orbital trauma. In the absence of direct facial or orbital trauma, nontranmatic subperiosteal orbital hematoma has rarely been reported in association with a sudden elevation of cranial venous pressure or venous congestion, systemic diseases associated with a bleeding diathesis and paranasal sinusitis. We report here on a rare case of subperiosteal orbital hematoma associated with ethmoid sinusitis, as was seen on CT imaging.
