Pyogenic Liver Abscess Secondary to Sigmoid Diverticulitis: An Unusual Presentation
1Southmead Hospital, North Bristol Trust, Bristol, United Kingdom.
Abstract:
Pyogenic liver abscesses, despite being a rare complication of diverticulitis and inflammatory bowel disease, are potentially serious life-threatening pathologies. Diverticular diseases can lead to disruption of the colonic mucosal barrier and can serve as a route for bacterial infection via the portal venous system. This patient had such a delayed presentation due to his atypical symptoms; he developed large abscess formation, detected by computed tomography, eventually requiring an ultrasound-guided drain followed by a colonoscopy. The present report describes an elderly gentleman who developed a bacterial liver abscess due to seeding of a commensal organism caused by sigmoid diverticulitis.
Insights
Pyogenic liver abscesses are rare but serious complications of diverticulitis. This case highlights a bacterial liver abscess caused by sigmoid diverticulitis in an elderly patient, emphasizing atypical presentations.
Area of Science:
- Gastroenterology
- Hepatology
- Infectious Diseases
Background:
- Pyogenic liver abscesses are uncommon but severe conditions.
- Diverticular diseases can compromise the colonic barrier, enabling bacterial spread via the portal system.
Observation:
- A case report of an elderly male presenting with atypical symptoms.
- Delayed diagnosis due to unusual clinical presentation.
- Computed tomography revealed a large liver abscess.
Findings:
- The liver abscess was attributed to bacterial seeding from sigmoid diverticulitis.
- The patient underwent ultrasound-guided drainage and subsequent colonoscopy.
- Commensal organisms were identified as the causative agents.
Implications:
- This case underscores the importance of considering diverticulitis as a potential cause of pyogenic liver abscesses.
- Highlights the need for thorough investigation in patients with atypical presentations.
- Emphasizes the role of imaging and endoscopic procedures in diagnosis and management.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
