摘要
Tc-99m pertechnetate scintigraphy is the modality of choice for diagnosis of Meckel%26apos;s diverticulum. Interpretation of Meckel%26apos;s scan identifies a focal area of radiopharmaceutical uptake in the anterior abdomen similar to normal gastric mucosa. The activity must be of the same pattern and intensity as gastric uptake. We present a 13-year-old patient with gastrointestinal bleeding and anemia. Tc-99m pertechnetate scintigraphy was performed and initial images did not show any abnormal tracer activity in the abdomen. However, imaging continued and a focal activity was detected on the right side of the abdomen 60 minutes delayed image. Follow laparascope operation the Meckel%26apos;s diverticulum was removed and the patient%26apos;s symptoms disappeared completely. It is suggest to pay special attention to delayed images (60 minutes or beyond) especially when earlier images are negative.
