Abdominal Variant of Lemierre’s Syndrome in a Patient with Pancreatic Adenocarcinoma

Lemierre’s syndrome is an illness characterized by internal jugular vein thrombophlebitis related to infectious agents, primarily Fusobacterium necrophorum. These bacteria, residing in both the oropharynx and the gastrointestinal tract, may lead to pylephlebitis, a serious condition that could result in the development of hepatic abscesses. This manifestation of the disease is regarded as the abdominal variant of Lemierre’s syndrome. Patients with gastrointestinal malignancies, especially those who undergo surgeries, are susceptible to the abdominal variant of Lemierre’s syndrome. Timely diagnosis is required to avoid the life-threatening complications of the abdominal variant of Lemierre’s syndrome. Diffusion-weighted magnetic resonance imaging (MRI) might be very useful in differentiating this disease from liver metastasis in patients with malignancies. Radiologists and clinicians need to be aware of this challenging condition to prevent misdiagnosis, since prompt treatment is often lifesaving.
