Diagnosis and Management of Lemierre's Syndrome Presented with Multifocal Pneumonia and Cerebral Venous Sinus Thrombosis.

A 27-year-old female patient initially presented with fever, myalgia, sore throat that progressed to multifocal pneumonia, and cerebral sinus venous thrombosis. A combination of upper respiratory symptoms with tooth infection, positive blood culture for Fusobacterium nucleatum, computed tomography (CT) chest finding of multifocal pneumonia, and magnetic resonance imaging (MRI) finding of internal jugular vein thrombosis (IJVT) and cerebral venous sinus thrombosis (CVST) suggested Lemierre syndrome. The patient was managed with fluids, antibiotics, and anticoagulants. The patient survived and discharged from the hospital. The patient's symptoms improved at 2 months of follow-up.
