A 64-year-old woman was transported to the emergency room with a headache and fever. She presented with a right ocular protrusion, hyperemia, and tenderness in the neck. Contrast-enhanced MRI of the head showed a high DWI signal in the bilateral sphenoid sinuses and contrast defects along the bilateral internal jugular and superior ophthalmic veins. ⋯ Surgery was performed for Lemierre's syndrome secondary to sphenoid sinusitis. The patient was treated with antibiotics and anticoagulant therapy, but a duodenal ulcer and brain abscess thereafter developed. However, multidisciplinary endoscopic and surgical treatment saved her life.
