In this short report, we describe a small series of adult patients with chronic appendicitis presenting with chronic right lower quadrant abdominal pain. The clinical presentation was unusual and atypical for classic appendicitis because of the absence of fever, peritoneal tenderness on focused graded compression of the abdomen, and leukocytosis. Computed tomography (CT) findings included the presence of an appendicolith and appendiceal thickening, without mesenteric infiltration, abscess, or collection. In this series, the appendicolith appeared to represent a marker rather than an actual cause of appendicitis. Focused CT scans with additional lung and bone windows proved optimal in detecting appendicoliths, which were not visible on the scout localizer scans, despite windowing modifications. Our findings suggest that chronic appendicitis may be a phenomenon unique to adults and should be included in the differential diagnosis of chronic right lower quadrant pain in patients seen in the emergency room setting. Surgery is curative in such patients, although expectant management is an alternative when tolerated by the patient.
