Idiopathic Orbital Pseudotumor: A Rare Case Report.

Orbital pseudotumor is a rare inflammatory condition affecting the orbit of the eye. It has diverse clinical manifestations. Although its exact etiology remains unknown, it is believed to involve an immune-mediated response. A 42-year-old male presented to the ophthalmology clinic with progressively worsening symptoms in his left eye, including pain, swelling, and blurry vision. He had no history of trauma or recent illness. Initial discomfort had escalated over three weeks. The patient had controlled hypertension but no known allergies. Examination showed eyelid edema, erythema, and mild anterior chamber cell, and flare in the left eye. Magnetic resonance imaging revealed orbital soft tissue enhancement, extraocular muscle thickening, and optic nerve involvement. Laboratory results showed elevated inflammatory markers. A diagnosis of orbital pseudotumor was made. The patient was treated with oral corticosteroids, resulting in symptom improvement and regression of inflammatory changes on follow-up. Orbital pseudotumor is a complex condition with diverse clinical manifestations. Its diagnosis requires a comprehensive approach involving clinical evaluation, imaging studies, and laboratory investigations.
