- Thoracic empyema is an infrequent complication of appendicitis that has rarely been reported in the literature. The case of a 6-year-old girl who was admitted for medical management of a perforated appendicitis is presented. Her clinical course was complicated by the development of an appendicular abscess and a subdiaphragmatic abscess leading to right-sided empyema and how it was managed surgically and medically. Thoracic empyema should be considered a potential cause of respiratory distress in patients with appendicitis. Furthermore, the abdomen should be carefully evaluated as a source of infection in patients with thoracic empyema without an underlying lung disease.
