目的分析胃间质瘤(GST)的CT表现,探讨CT对其临床诊断价值。方法回顾性分析经手术病理证实的25例GST患者的CT及相关临床资料。结果 GST的CT表现为软组织肿块,肿块向胃腔内、外或同时向腔内外突出,肿块的密度均匀或不均匀伴有大小不等,形态不一;增强后,肿块均匀强化或不规则强化,可见中心坏死及远处转移灶。本组病例中良性7例,肿块直径多数小于5 cm,边界较清楚,CT显示多为均匀强化;恶性13例,肿块直径多数大于5 cm,边界欠清楚,CT显示为不规则强化,肿块内有坏死表现或转移灶。结论 CT可清楚显示肿块的外部形态、内部改变及其与周围脏器的关系,对GST的定位定性诊断及鉴别诊断具有重要价值。
Objective To analyze the CT findings of gastric stromal tumors (GST) and investigate the clinical value of CT in its diagnosis. Methods The CT and related clinical data of 25 GST patients confirmed by surgery and pathology were retrospectively analyzed. Results The CT findings of GST were soft tissue mass. The masses of the masses were protruding to the inside and outside of the gastric cavity at the same time or outside of the cavity. The density of the masses was uneven or uneven with different sizes and shapes. After the enhancement, the masses were uniformly or irregularly strengthened , Visible necrosis and distant metastasis. The group of benign cases in 7 cases, the majority of tumor diameter less than 5 cm, the border is clear, CT showed more uniform enhancement; malignant in 13 cases, the majority of tumor diameter greater than 5 cm, the border is not clear, CT showed irregular enhancement, There are signs of necrosis or metastases. Conclusion CT can clearly show the external shape and internal changes of lumps and their relationship with the surrounding organs. It is of great value for the qualitative diagnosis and differential diagnosis of GST.
