【摘要】 目的探讨胃神经鞘瘤的CT和钡透表现及其诊断价值。方法对8例经手术病理证实的胃神经鞘瘤并结合文献进行回顾性分析。8例均行CT平扫,增强6例;5例行上消化道钡透检查。结果胃底2例,胃体小弯侧4例,胃窦部2例。病变主要分为3种类型:局灶性结节或肿块型(4例),胃壁局限增厚型(2例),巨块型(2例)。结论与钡透相比,CT能更准确地显示肿瘤形态、部位、内部结构及与邻近结构的关系,正确辨认胃神经鞘瘤3种主要类型,结合钡透表现,对部分病例可做出提示性诊断。更多还原

【Abstract】 Objective To study the value of CT and barium radiograpy in diagnosis of gastric schwannoma.Methods A retrospectiveanalysis was made on imaging of 8 patients with pathologically approved gastric schwannoma.Plain abdominal CT scan was performed in all patients, additional enhanced CT scan was carried out in 6 cases and barium radiography of upper digestive tract was carried out in 5 cases. Results The lesions localized in fundus ventriculi in 2 cases, curvatura ventriculi minor in 4 cases and pars pylorica in 2 cases. Three main types were seen: localized mass type (n=4), localized thickening of gastric paries type (n=2) and huge mass type (n=2).Conclusion In comparison with barium radiography of upper digestive tract, CT can accurately demonstrate the shape, the location and internal structure of lesions.Three main patterns of this lesion also can be showed clearly by CT scans and suggestive diagnosis can be made in some patients combined with barium radiography of upper digestive tract images.更多还原
