Stump appendicitis is an inflammation of appendiceal remnant after incomplete appendectomy. However, the inclusion of appendectomy in a patient’s medical history often obfuscates a diagnosis of appendicitis, causing a delay in diagnosis and potentially leading to increased morbidity. Awareness of stump appendicitis can help radiologists distinguish this rare condition from more common entities. We report two cases of stump appendicitis that were correctly identified at the patients’ time of presentation to the emergency department. In one case, the patient presented with recurrent stump appendicitis. In this case series, we discuss the radiographic features, clinical considerations, and treatment of stump appendicitis.
