Pyogenic Liver Abscess Following an Uncomplicated Colonoscopy

Pyogenic liver abscess is a potentially devastating clinical entity associated with significant morbidity and mortality([1]). A myriad of causes for liver abscess have been described including intra-abdominal infections such as diverticulitis([2]). Due to a non-specific presentation, clinicians often require a high level of suspicion in their diagnosis of this condition. A handful of cases of liver abscess have been described following colonoscopy which was usually a complicated procedure or one where multiple biopsies had been taken([3,4]). The case of a patient presenting pyrexia of unknown origin one week after undergoing an uncomplicated colonoscopy in which no biopsies were taken is reported. She was ultimately diagnosed with a pyogenic liver abscess. LEARNING POINTS: Pyogenic liver abscess is an important differential when investigating pyrexia of unknown origin. Liver abscesses can rarely occur following colonoscopy.
