Nontraumatic Subperiosteal Orbital Hematoma in a Patient With Behcet Disease.

Orbital subperiosteal hematomas are commonly caused by facial trauma. Nontraumatic subperiosteal orbital hematomas (NTSOHs) are rare but may occur in patients with underlying medical diseases. A 71-year-old woman presented to the emergency department with a 5-day history of left periorbital pain and proptosis. She was known to have Behcet disease and presented with no recent trauma. Clinical features and computed tomography findings aided in establishing the diagnosis of an NTSOH. The hematoma was evacuated via sub brow incision. After surgery, the patient's clinical symptoms resolved and did not recur during the 12-month follow-up period. On the basis of the findings of this case, the authors conclude that patients diagnosed with diseases such as bleeding disorders or autoimmune vasculitis should consider visual symptoms as a sign of an NTSOH. Patients who diagnosed with disease experience visual disturbance, periorbital pain, or periorbital swelling should undergo early surgical treatment for spontaneous NTSOH to avoid permanent visual loss.
