[目的]探讨胃炎症性肌纤维母细胞瘤(IMT)的CT表现。[方法]回顾性分析6例胃IMTs的CT检查资料,所有病例均经外科手术病理证实。[结果]肿瘤发生部位以胃体为最常见(5/6),其次为胃底(1/6),无发生在胃窦的病例;肿瘤呈肿块结节型、胃壁增厚型或肿块结节伴邻近胃壁增厚型,瘤体大小不一,呈软组织密度,均匀或不均匀,瘤体内可出现小的坏死灶,钙化可见但较少见;动态增强扫描除坏死灶无强化外,肿瘤强化均较明显;肿瘤边界大部欠清,胃浆膜层、胃周脂肪间隙可受浸润,尚未发现胃周、腹膜后等淋巴结肿大,亦未发现其他脏器转移等征象。[讨论]胃IMT的CT征象较多,有一定的特征性,但目前确诊上仍需依靠病理。
[Objective] To investigate the CT manifestations of gastric inflammatory myofibroblastic tumor (IMT). [Method] The CT examination data of 6 cases of stomach IMTs were retrospectively analyzed. All the cases were confirmed by surgical pathology. [Results] The most common site of tumor was gastric body (5/6), followed by gastric fundus (1/6), and no cases occurred in gastric antrum. The tumors were nodular, gastric thickening or mass knot Adjacent to the gastric wall thickened type, the tumor size varies, soft tissue density, uniform or uneven, small necrotic lesions may appear in the tumor, calcification can be seen but rare; dynamic enhanced scan in addition to no enhancement of the dead focus, the tumor And most of the tumor border is not clear. Most of the gastric mucosa and perivascular adipose tissue can be infiltrated. No lymphadenopathy such as gastric peritoneum and retroperitoneum has been found and no signs of other organs metastasis have been found. [Discussion] There are more CT signs of gastric IMT, there are certain characteristics, but the diagnosis is still dependent on the pathology.
