Subperiosteal Orbital Hemorrhage

Subperiosteal orbital hemorrhage is an uncommon condition that may be caused by direct trauma or various behaviors that result in increased venous pressure, such as the Valsalva maneuver. Its name describes the pathology and suggests the imaging findings.

CT and MRI will show a well-defined blood collection in the orbit, usually superiorly, that displaces the conal fat and extra-ocular muscles. Differential considerations include metastasis, lymphoma, or orbital pseudotumor.
