# The Hidden Diverticula: A Case Report on Appendiceal Diverticulosis

## TL;DR

A rare case of appendiceal diverticulosis is reported, highlighting its potential link to neoplasia and the importance of thorough diagnosis.

## Contribution

This case report adds to the limited literature on appendiceal diverticulosis and its clinical implications.

## Key findings

- Appendiceal diverticulosis was found in a 54-year-old male with left flank pain and dysuria.
- Histopathology confirmed DA with acute inflammation and fibroblast proliferation but no malignancy.
- The case emphasizes the need for considering DA in differential diagnoses and timely surgical intervention.

## Abstract

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.
