Isolated Crohn’s Disease of the Appendix Presenting as Acute Appendicitis in a 60‐Year‐Old South Asian Female: A Case Report, Review of Literature, and Follow‐Up Recommendations

Abstract

The isolated appendiceal Crohn’s disease without preceding bowel symptoms is a rare phenomenon, especially in older patients. In this case report, we present a 60‐year‐old female with isolated appendiceal Crohn’s disease presenting with acute appendicitis. She presented with classical features of appendicitis with elevated inflammatory markers. She underwent an appendectomy which showed an excessively swollen, oedematous, and reddish appendix with swelling extending to the base of the caecum. Histological evaluation was suggestive of Crohn’s disease, and subsequent colonoscopy was unremarkable. Following appendectomy, she was asymptomatic without any recurrence of disease. The atypical morphological appearance of the appendix should raise suspicion of Crohn’s disease. This case highlights the importance of histopathological analysis of the specimen, especially in abnormal clinical findings. The prognosis of such patients seems to be good, and additional treatment is rarely needed.
