title: Intestinal neoplasm mimicking a Meckel's diverticulum on scintigraphic imaging.
abstract: A 33-year-old man presented with colicky, intermittent, midabdominal pain with nausea and vomiting. A Tc-99m pertechnetate abdominal scan was performed and revealed a focal area of increased uptake in the midabdomen associated with dilated proximal loops of small bowel. Surgery revealed a high-grade partial obstruction of the midportion of the jejunum secondary to an annular adenocarcinoma of the jejunum. This is the first known report of abnormal Tc-99m pertechnetate accumulation in an adenocarcinoma of the small bowel.
