DISSEMINATED ISLANDS OF GASTRIC-MUCOSA IN JEJUNUM AND ILEUM DETECTED BY TECHNECTIUM-99M-PERTECHNETATE SCINTIGRAPHY

Disseminated islands of gastric mucosa are very rare in the small inte stine. The secretion of hydrochloric acid can lead to ulceration which results in gastrointestinal bleeding, It is often difficult to locali ze the focus in case of gastrointestinal blood loss especially in the small bowel, Technetium-99m-pertechnetate scintigraphy may be a helpfu l tool in detecting ectopic gastric mucosa, We report a case of a 21-m o-old boy with recurrent gastrointestinal bleeding. By using pertechne tate scintigraphy, extensive tracer accumulation in the jejunum and pr oximal ileum was detected, Histologically, multiple islands of ectopic gastric mucosa were found in about 50 excited mucosal and transmural biopsies, The unusual finding of disseminated accumulation of Tc-99m-p ertechnetate in the small intestine was the diagnostic clue for such a rare disease.
