目的：探讨小肠间质瘤的螺旋 CT 表现及诊断价值。方法回顾性分析经手术及病理证实的小肠间质瘤19例，所有病例均行 CT 平扫及增强双期或三期扫描，2例行 CTA 后处理重建。结果19例小肠间质瘤中，2例位于十二指肠，6例位于空肠，10例位于回肠，1例多发位于空、回肠。良性3例，潜在恶性1例，恶性15例。全部19例 CT 表现为向肠腔外生长的肿块。良性者，平扫密度均匀，边缘清晰，可见轻度均匀强化。恶性者，平扫肿块边缘清晰12例，4例边缘模糊，增强扫描见轻至中度强化14例，明显强化2例，2例肿块内可见粗大的供血血管。多数内见无强化坏死区，坏死区呈偏心性且达边缘6例，坏死囊变明显呈囊肿样及肿块内出现气体、液平面各1例。结论螺旋 CT 对于小肠间质瘤的定位、定性诊断及指导临床治疗和预后的评估都有重要的价值。

Objective:To investigate the CT findings and the diagnostic value of spiral CT in small intestine stromal tumor(SIST). Methods:The spiral CT materials of 19 patients with surgically and pathologically proved SIST were collect-ed and retrospectively analyzed. Both plain and enhanced CT scans were performed in all cases. CTA were performed in 2 cases. Results:The tumors originated from the duodenum(n = 2),jejunum(n = 6),ileum(n = 10). Multiple tumors were found to originate from the jejunum and ileum(n = 1). Among these SIST included benignancy(n = 3),potential malignancy(n = 1),and malignancy(n = 15). All tumors showed exophytic growth. The benign lesions(n = 3)showed clear margins and homogeneous density and slight enhancement. The malignan lesions showed clear margin or ill-defined margin,mild to moderate enhancement and marked enhancement. The dilated vessels of tumors were found in 2 cases. Ne-croses were observed in most cases,1 case was cystic mass,gas and fluid level within the mass were seen in 1 case. Ec-centric necrotic areas close to the edge of masses in 6 cases. Conclusion:Spiral CT has an important value in SIST localiza-tion and qualitative diagnosis,which is helpful in guiding clinical treatment and evaluation of prognosis.
