目的：探讨多层螺旋CT对小肠间质瘤征象，评价其诊断价值。方法回顾性分析13例经手术和病理证实的小肠间质瘤多层螺旋CT表现。结果13例小肠间质瘤，其中良性2例，潜在恶性1例，恶性10例。病灶直径3～37cm，平均23cm。良性病灶2例均小于5 cm，恶性病灶8例大于5 cm，7例呈圆形及类圆形，6例有分叶。轻度强化2例，中度强化3例，明显强化8例，其中5例可见供血动脉。较大的肿块常发生坏死、囊变，增强扫描囊变区不强化，实性部分强化，3例坏死区为偏心性，1例坏死区内可见气体，2例合并腹腔内大量腹水。结论小肠间质瘤的多层螺旋CT表现具有一定的特征，对本病的诊断及鉴别诊断有重要价值。

Objective To investigate the CT characteristics and the diagnostic value of MSCT in small intestine stromal tumor ( SIST) .Methods The MSCT materials of 13 patients with surgically and pathologically proved SIST were collected and retrospectively ana -lyzed.Results Among these SIST, 10 of them were malignant , 1 was potential malignant , and 2 were benigh.The former was usually 3~37 cm in diameter as well ,with average 23 cm.The 2 benign cases showed clear margins with slight enhancement and <5 cm in diameter . The 11 malignant cases showed ill -defined margin,mild to moderate enhancement and marked enhancement and >5cm in diameter.The di-lated vessels of tumors were found in 5 cases.The tumors were round or oval in 7 cases, with leaf shape in 6 cases.Necrotic and cystic areas were found in the malignant lesions .Remarkable enhancement was found in the parenchyma of the tumor , while no enhancement was found in the necrosis and cystic areas of the tumors .Eccentric necrotic areas close to the edge of masses in 3 cases and gas was found in 1 case. Ascite was found in 2 cases.Conclusion Multi-slice spiral CT has an important value in SIST ocalization and qualitative diagnosis ,which is helpful in guiding clinical treatment and evaluation of prognosis .
