title: Extensive heterotopic gastric mucosa of the small intestine: imaging with99mTc-sodium pertechnetate SPECT/CT enterography.
abstract: Extensive heterotopic gastric mucosa of the small intestine is a rare, but potentially life-threatening condition characterized by multifocal or long-segment heterotopic gastric mucosa within the bowel lumen that is often associated with other anomalies including malrotation and annular pancreas. Although the imaging findings are characteristic, this entity may be unrecognized due to its unusual imaging appearance and rarity. CT or MR enterography and99mTc-sodium pertechnetate scintigraphy can provide complementary information that enables specific diagnosis and accurate assessment of disease extent. We present a case of extensive heterotopic gastric mucosa of the small intestine imaged by simultaneous, combined99mTc-sodium pertechnetate single photon-emission computed tomography (SPECT)/CT enterography to both familiarize the reader with the condition and describe an imaging strategy that enables specific diagnosis and assists with treatment planning.
