Fishbone perforating Meckel's diverticulum: an acute appendicitis mimicker.

ABSTRACT

Perforation of Meckel's diverticulum by a foreign body is rare, but when it occurs, it can mimic acute appendicitis, leading to diagnostic challenges. We present a case of a 45-year-old male initially diagnosed with acute appendicitis, but intra-operative exploration revealed a perforated Meckel's diverticulum with a fish bone. Meckel's diverticulum perforation remains diagnostically elusive, highlighting the need for intra-operative vigilance in cases of inconsistent findings like the presence of bilious fluid in the abdominal cavity. This case report underscores the importance of considering perforated Meckel's diverticulum in the differential diagnosis of right iliac fossa pain and the necessity of surgical exploration for atypical presentations to ensure timely diagnosis and appropriate management.
