胃肠道平滑肌肿瘤的影像诊断

目的:探讨CT及胃肠钡餐检查在胃肠道平滑肌肿瘤鉴别诊断中的应用价值。方法:收集15例经手术病理证实的胃肠道平滑肌瘤(4例)和平滑肌肉瘤(11例)作回顾性分析。15例均行CT检查,8例行胃肠道钡餐造影检查。结果:胃肠道平滑肌肿瘤多好发于胃,除直接浸润和远处转移提示为恶性外,肿瘤不规则或分叶状、不均匀强化、中心坏死、溃疡形成以及临近胃肠壁不均匀性增厚提示平滑肌肉瘤可能性大。结论:CT在胃肠道平滑肌肿瘤的诊断与鉴别诊断中有明显的应用价值,优于胃肠道钡餐检查。

Object：To evaluate the differentiating diagnostic value of CT and the barium meal study efficacy in the gastrointestinal smooth muscle tumors. Materials and Methods： 15 cases of gastrointestinal tract confirmed by pathology were examinated with CT,8 cases with barium meal study. Results： The stomach was the commonest site of the gastrointestinal smooth muscle tumors. In addition to the features of direct invasion and distant metastasis, the irregular or lobulated contour, heterogeneous enhancememt, centre necrosis, ulceration and irregular thicken wall connected the masses of the gastrointestinal tract were favored the possibility of leiomyosarcoma. Conclusion： The CT characteristic differentiating diagnostic value of the gastrointestinal smooth muscle tumors were found, CT examination significant superior to the barium meal study.
