In gastrointestinal-variant Lemierre syndrome, Fusobacterium nucleatum can cause pylephlebitis and liver abscesses. We report a 62-year-old woman presenting with abdominal pain and altered mental status. Abdominal computed tomography showed hepatic lesions and thrombosis in the superior mesenteric and portal veins. Magnetic resonance cholangiopancreatography showed multiple cystic hepatic masses suspicious for abscess vs metastases. Malignancy workup was unrevealing. F. nucleatum grew on both blood and ultrasound-guided liver aspirate cultures. Twelve weeks of antibiotics and anticoagulants resolved her condition. Given the high mortality rates, prompt detection and treatment of gastrointestinal-variant Lemierre syndrome is critical to delivering quality, patient-centered care.
