Clinics in diagnostic imaging (162). Meckel's diverticulum

ABSTRACT

A 28-year-old Chinese man presented with acute bleeding per rectum. Computed tomography showed a posterior outpouching arising from the distal ileum. The outpouching had hyperaemic walls, but no active contrast extravasation was detected. Technetium-99m pertechnetate scintigraphy showed focal areas of abnormal uptake in the right side of the pelvis, superior and posterior to the urinary bladder. These areas of uptake appeared simultaneously with the gastric uptake and demonstrated gradual increase in intensity on subsequent images. The diagnosis of Meckel's diverticulum was confirmed on surgery and the lesion was resected. The clinical and imaging features of Meckel's diverticulum are discussed.
