Visualization of a Photopenic Lesion Secondary to a Giant Small Bowel Diverticulum with Fecal Retention During Meckel's Scintigraphy

摘要

A 30-year-old man with a second episode of melena had previous workups, including gastroscopy and colonoscopy, that failed to localize a source of bleeding. Tc-99m pertechnetate abdominal scintigraphy showed a giant photopenic lesion in the suprapubic region. An upper gastrointestinal and small bowel series obtained after Meckel's scintigraphy showed a huge small bowel diverticulum in the midanterior pelvis. This case shows how a giant small bowel diverticulum with fecal retention can produce images suggestive of a photopenic lesion during Meckel's scintigraphy.
