- Abstract: Objective To explore the value of multi-slice spiral CT for the diagnosis of heterotopic pancreas in the gastrointestinal tract, and to analyze misdiagnosed lesions. Methods Eighteen cases diagnosed with heterotopic pancreas by 64-slice spiral CT before operation were enrolled in the study for a retrospective analysis, and their pathological results had been obtained. Results There were 19 lesions in the 18 patients. Eleven lesions were found in 10 patients in correct diagnosis group, including 7 lesions in the gastric mucosa, 3 lesions in the duodenum and 1 lesion in the ileum. The sign of central umbilication was observed in 5 of the above lesions. In misdiagnosis group, a total of 8 lesions were found in 8 patients, including 3 lesions in the gastric mucosa or submucosa, 4 leisons in the duodenum and 1 lesion in the lower esophagus. The pathological results indicated that 3 of the 8 lesions were inflammatory, and that there were 2 neoplastic lesions (gastrointestinal?stromal?tumor and neuroendocrine tumor), 1 heterotopia of gastric fundus gland, 1 gastric mucosal prolapse and 1 Peutz-Jeghers polyp. The imaging manifestations of heterotopias of gastric fundus gland and stromal tumor were similar to central umbilication. Conclusion The majority of lesions in correct diagnosis group are located in the stomach and duodenum. The manifestations of part of the lesions in misdiagnosed group are similar to central umbilication, which may be one of the causes of misdiagnosis. In addition, inflammatory lesions account for a large proportion of misdiagnosed cases, suggesting that gastrointestinal inflammatory lesions should be considered in the differential diagnosis of heterotopic pancreas.
