Bleeding Meckel diverticulum associated with a vitellointestinal artery aneurysm found on preoperative angiography: report of a case

Meckel's diverticulum: Unusual cause of significant bleeding in an adult male

Meckel's diverticulum is a common congenital gastrointestinal malformation affecting 2% of the general population. Most affected patients are asymptomatic, and excessive bleeding causing a significant drop in hemoglobin count is an uncommon complication of Meckel's diverticulum, especially in adult patients. Herein, we present an adult case of Meckel's diverticulum that nearly led to hemodynamic instability. Laparotomy and segmental small bowel resection were critical in treating the patient.

Radiologist's perspective for the Meckel's diverticulum and its complications

The Meckel's diverticulum is the commonest congenital anomaly of the gastrointestinal tract, often presenting with complications such as gastrointestinal bleeding, intussusception, bowel obstruction and diverticulitis, which are often misdiagnosed. Imaging plays an important role in the early diagnosis and characterization of these conditions and is very helpful in decision making. The Meckel's diverticulum and its complications have myriad presentations and appearances on various imaging modalities. Thus, sound knowledge of the anatomy, embryology, clinical presentation, imaging characteristics and complications is crucial to the practice of abdominal imaging. We present a review of the literature and current radiological practices in the diagnosis and management of the Meckel's diverticulum and its various complications with special emphasis on the imaging of various complications, mimickers and pathological correlation.
