Case Report

Introduction
Cecal duplication cysts are the rarest gastrointestinal duplication cysts. The vast majority of cases were discovered during childhood and before the age of two years, with only a few cases mentioned in adults.

Cecal duplication cyst presents with various clinical symptoms, including abdominal mass, intestinal obstruction, rectal hemorrhage, acute appendicitis, and intestinal obstruction. However, most cases (50%) present with a palpable mass.

Most duplication cysts communicate with the gastrointestinal tract, with limited published cases of non-communicating duplication cysts. We present a 23-year-old man who presented with abdominal pain and was diagnosed with cecal duplication cyst. The adult age at symptom onset, non-communicating cyst, and cecal location contribute to the rarity of this case.
