Pyogenic Liver Abscess Secondary to Appendicitis

Abstract: Liver abscess is a rare disease, primarily affecting men around 60 years old with multiple comorbidities, notably diabetes, liver transplantation, and digestive neoplasia. Contamination of the liver parenchyma can occur via the biliary tract or hematogenous route (arterial or portal), or directly by contiguity. It is a bacterial, parasitic, or very rarely fungal infection. Liver abscesses of biliary or portal origin are often polymicrobial. Liver abscesses of systemic origin are generally monomicrobial, while fungal liver abscesses are rarer and affect immunocompromised patients. Treatment is based on drainage of the liver abscess, prolonged antibiotic therapy, and treatment of the entry point. We report here the case of a 55-year-old woman presenting a pyogenic liver abscess, secondary to radiologically confirmed acute appendicitis. The objective of this article is to describe a rare cause of liver abscess and review the literature, to contribute to the diagnosis and management of future similar cases.
