目的分析胃脂肪瘤影像学特征。方法回顾性分析13例胃脂肪瘤临床表现,总结钡餐、CT和MRI检查时病灶大小、边缘、密度和信号及溃疡形成等影像学特征。结果13例胃脂肪瘤均为单发,起源于胃窦、底、体部黏膜下层,向腔内生长。6例钡餐检查表现黏膜下低密度充盈缺损,局部胃壁柔软,3例伴溃疡、呈“牛眼征”。8例CT扫描见大小不等圆形、卵圆形低密度肿块,CT值-50~-120 HU,4例显示溃疡。2例MRI T1/T2WI呈高信号、T2抑脂呈低信号的脂肪特征。结论影像学各项检查对胃脂肪瘤的诊断各具特点,有一定的诊断价值。
Objective To analyze the imaging features of gastric lipoma. Methods The clinical manifestations of 13 cases of gastric lipoma were retrospectively analyzed. Imaging features such as size, margins, density, signal and ulceration of barium meal, CT and MRI were summarized. Results All 13 gastric lipoma were single, originated from the antrum, basal and submucosal layers and grew into the cavity. Six cases of barium meal examination showed submucosal filling defect, local soft stomach, 3 cases with ulcer, was “bull’s eye sign.” 8 cases of CT scan to see the size ranging from round, oval low-density mass, CT value of -50 ~ -120 HU, 4 cases showed ulcers. Two cases of MRI T1 / T2WI showed high signal, T2 fat suppression showed low signal fat characteristics. Conclusion The imaging examination of gastric lipoma have their own characteristics, have a certain diagnostic value.
