目的探讨多层螺旋CT小肠造影诊断小肠恶性间质瘤(small intestinal stromal tumor,SIST)的价值。方法回顾性分析10例经手术组织病理和免疫组织化学证实SIST患者的多层螺旋CT小肠造影资料。结果多层螺旋CT小肠造影术前诊断SIST 9例(14个病灶),定性诊断符合率90%,定位诊断符合率100%,1例单发病灶误诊为小肠平滑肌瘤。结论多层螺旋CT小肠造影对诊断SIST有临床价值。
Objective To investigate the value of multislice spiral CT in the diagnosis of small intestinal stromal tumor (SIST). Methods Retrospective analysis of 10 cases of SIST patients by histopathology and immunohistochemistry confirmed by multi-slice spiral CT small bowel angiography data. Results There were 9 cases (14 lesions) of SIST diagnosed by multislice helical CT. The coincidence rate of qualitative diagnosis was 90%. The coincidence rate of localization diagnosis was 100%. One case of single lesion was misdiagnosed as small intestinal. Conclusion Multislice spiral CT small bowel angiography has clinical value in the diagnosis of SIST.
