Recurrent aseptic liver abscesses in a patient with Crohn's disease: True infection or a Crohn's flare?

A liver abscess is identified as a rare extraintestinal manifestation of Crohn's disease, with an incidence of approximately 150 in 100,000 patients with this condition. In many of these patients, infectious causes are identified, and the patient's condition is often noted to improve with antibiotics. An aseptic abscess (AA) is an increasingly recognized entity, especially in patients with inflammatory bowel disease, where repetitive evaluations to identify the infectious cause are futile. The average age of diagnosis for an AA is 29 years. The most common site is the spleen, followed by the lymph nodes and then the liver. In this study, we present a unique case of extensive aseptic liver abscesses extending into the pleural cavity in a young patient with Crohn's disease.(c) 2021 Pan-Arab Association of Gastroenterology.
