目的探讨螺旋CT对胃间质瘤(GST)的诊断及鉴别诊断的价值。方法回顾性分析经手术、病理及免疫组化证实的18例GST的CT表现。结果 18例肿瘤均为单发,其中3例恶性,6例低度恶性,9例良性。平扫密度均匀11例,平扫密度不均匀7例,增强病变呈中度或明显强化,11例病变见溃疡或囊性变,所有病例均未见淋巴结肿大。结论 GST的CT表现具有一定的特点,螺旋CT对GST的诊断及鉴别诊断具有重要价值。
Objective To investigate the value of spiral CT in the diagnosis and differential diagnosis of gastric stromal tumor (GST). Methods The CT findings of 18 cases of GST confirmed by surgery, pathology and immunohistochemistry were retrospectively analyzed. Results All the 18 tumors were single, of which 3 were malignant, 6 were low-grade and 9 were benign. Eleven patients had even density, 7 patients had uneven density, enhanced or moderate enhancement, 11 patients had ulceration or cystic degeneration, and no lymph nodes were found in all cases. Conclusion The CT findings of GST have certain characteristics. Spiral CT is of great value in the diagnosis and differential diagnosis of GST.
