Abstract:
Meckel's diverticulum (MD) is the most common gastrointestinal anomaly with heterotopic mucosa in 60% of cases. 99m technetium-pertechnetate scintigraphy is a sensitive tool for detection of MD containing heterotopic gastric mucosa. It is usually located in the right lower quadrant or umbilical region and less frequently in other quadrants. A mobile or wandering MD is a rare clinical presentation and may pose a diagnostic dilemma. However, presence of temporal correlation with gastric activity and compactness of focus during wandering period could make this riddle easy.
