Klebsiella pneumoniae-induced liver abscess in a patient with ulcerative colitis: a case report and review of the literature

This case describes a Klebsiella pneumoniae-associated hepatic abscess in a patient with ulcerative colitis, a combination not previously reported in literature. This case highlights the extraordinary rarity of Klebsiella pneumoniae-associated hepatic abscesses in ulcerative colitis populations. Clinicians should consider this diagnosis in patients with ulcerative colitis presenting with right upper quadrant pain accompanied by pyrexia, even in the absence of classic risk factors. Expedited abdominal imaging and targeted antimicrobial therapy are essential to prevent systemic complications.
