A 37-year-old man presented with fever and a red, painful right eye. He had proptosis, conjunctival chemosis, and ophthalmoplegia OD. The patient had extremely poor dentition and had self decompressed a dental abscess prior to admission. Magnetic resonance imaging of the brain and orbital revealed extraocular muscle engorgement and a dilated superior ophthalmic vein OD. Orbital echography revealed a lack of flow in the right superior ophthalmic vein. An extensive hematologic evaluation for infection and inflammation was negative. A chest radiograph showed a lung abscess for which he received intravenous antibiotics. Over time, the periorbital erythema, ophthalmoplegia, proptosis, and pain resolved. Repeat MRI showed resolution of the orbital findings and repeat chest x-ray showed resolution of the left upper lobe abscess.
