Core Tip
Core Tip: A Morgagni hernia (MH), a congenital gap in the diaphragm, may only become evident later in life. Initially small, this defect enlarges over time due to increased intra-abdominal pressure. Although it usually remains asymptomatic, a MH can lead to severe gastrointestinal or pulmonary complications. We describe the case of a previously asymptomatic 76-year-old woman who underwent a routine follow-up colonoscopy. Unexpectedly, the procedure led to a colonic perforation due to a previously undiagnosed large MH. This rare complication emphasizes the need for endoscopists to be vigilant in suspecting and diagnosing potential intra-procedural complications associated with this condition.
