Radionuclide Imaging of Jejunoileal Duplication Cyst in a Child

A 2-and-a-half-year-old boy was hospitalized for painless bloody stools for the last few months. The patient underwent Tc-99m pertechnetate scintigraphy to confirm the presence of a Meckel diverticulum. Images showed generalized increased uptake in the inferior area of the stomach. At laparotomy, a 70-cm long jejunoileal cystic and tubular duplication was resected. Histologic examination showed gastric mucosal lining and hemorrhagic areas. The importance of Tc-99m pertechnetate scintigraphy for the diagnosis in heterotopic gastric mucosa is highlighted.
