M Tracy et al. JPGN Reports 2021; Free Access: Where Did the Blood Go?: A Meckel’s Diverticulum Bleed Without Hematochezia or Melena doi: 10.1097/PG9.0000000000000119

In this case report, a 2 yo with acute anemia along with acute on chronic abdominal pain was diagnosed with a Meckel’s diverticulum. After diagnostic studies, “a blood-filled mass arising from the ileum was identified and resected by the surgical team. Pathology was consistent with Meckel’s diverticulum with heterotopic gastric mucosa.”

My take: This is a rare presentation of a Meckel’s diverticulum. Besides bleeding, per the authors, “common presentations of Meckel’s diverticulum include diverticulitis/perforation (16%-20%), bowel obstruction (about 14%), and intussusception (12%).”
