The purpose of this study was to characterize the computed tomographic (CT) findings of heterotopic pancreas of the stomach.
CT scans of six surgically proven cases of heterotopic pancreas of the stomach were reviewed. Three were dynamic spiral CT scans, with both arterial dominant and late phase scans. In other three, both unenhanced and contrast-enhanced scans were obtained by using conventional techniques. Particular attention was given to the enhancement of the heterotopic pancreas. Pathologic and surgical findings were correlated with CT findings.
The locations were in the gastric antrum in five cases and in the mid-body in one. Size ranged from 1 cm to 3 cm (mean = 2.1 cm). Three cases showed homogeneous, strong enhancement similar to the pancreas and consisted mainly of pancreatic acini with the same histologic features as the normal pancreas. Two cases showed poor enhancement and consisted mainly of ducts and hypertrophied muscle; pancreatic acini were a minor component. In one case appearing as a cystic lesion on CT, a pseudocyst was found with many ducts and some nests of pancreatic acini.
Heterotopic pancreas of the stomach showed a diverse spectrum of CT findings. Good understanding of these CT findings may be helpful in making a correct diagnosis.
本研究旨在描述胃异位胰腺的计算机断层扫描（CT）表现。
回顾了6例经手术证实的胃异位胰腺的CT扫描结果。其中3例为动态螺旋CT扫描，包括动脉期和延迟期扫描。另外3例采用传统技术进行平扫和增强扫描。特别关注异位胰腺的强化情况。将病理和手术结果与CT表现进行关联。
5例位于胃窦部，1例位于胃体中部。大小范围为1 cm至3 cm（平均 = 2.1 cm）。3例表现为与胰腺相似的均匀、明显强化，主要由胰腺腺泡组成，组织学特征与正常胰腺相同。2例强化不佳，主要由导管和肥厚的肌肉组成；胰腺腺泡为次要成分。1例在CT上表现为囊性病变，病理发现为假性囊肿，伴有许多导管和一些胰腺腺泡巢。
胃异位胰腺的CT表现多样。对这些CT表现的充分了解可能有助于做出正确诊断。
