The Hidden Diverticula: A Case Report on Appendiceal Diverticulosis.

Diverticulosis of the appendix (DA) is a rare condition, often asymptomatic and incidentally discovered, with a significant association with neoplasia. The prevalence of neoplasia in specimens without DA versus those with DA was 1.28% and 26.94%, respectively. Here, we discuss a case of a 54-year-old male presented with left flank pain and dysuria. Examination showed left renal angle tenderness and leukocytosis. CT scan revealed a left ureteric stone and an enlarged appendix. The urology team placed a double-J catheter, and surgical consultation led to an appendectomy. Histopathology confirmed DA with acute inflammation, serositis, and fibroblast proliferation without malignancy. This case underscores the need to consider DA in differential diagnoses and the importance of thorough histopathological examination and timely surgical intervention.
