An Uncommon Location of Meckel’s Diverticulum: A Rare Entity

Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract. It affects 2% of the general population.[1] A 11-month-old male child presented with complaints of passing a black tarry color stool for 3 days. Meckel's scan showed a focal area of abnormal tracer uptake in the lower abdomen, just above the urinary bladder [Figure 1]. On laparotomy, a Meckel's diverticulum was found on the mesenteric border, around 30 cm proximal to the ileocecal junction supplied by the vitelline artery at the apex [Figure 2]. Resection and anastomosis were done. The histopathology report revealed Meckel's diverticulum with heterotopic gastric tissue [Figure 3]. The mesenteric border location of Meckel's diverticulum is very rare, and it is more alarming because it may erode the mesentery and its vasculature during diverticulitis causing devastating complications.[2]Figure 1: Meckel's scan showing an increased flow and abnormal tracer uptake in lower abdominal region, just above the urinary bladder (black arrow)Figure 2: Intraoperative photograph showing Meckel's diverticulum on the mesenteric border (yellow arrow) and vitelline artery at the apex (black arrow)Figure 3: Higher magnification shows diverticulum lined by intestinal epithelium and sub epithelium containing gastric foveolar or oxyntic glands (H and E; ×200)Declaration of patient consent The authors certify that they have obtained all appropriate patient consent forms.
