胃血管球瘤的CT诊断价值

CT diagnosis of gastric glomus

目的：探讨胃血管球瘤的CT诊断价值，并对文献进行复习，以提高对其认识。方法：回顾性分析5例（女3例，男2例，年龄49～72岁，平均61岁）经手术病理证实的胃血管球瘤的CT特征（如病变部位、大小、CT值、强化曲线、供血动脉与引流静脉等表现）。采用CT平扫加动态增强，并进行MPR重建。结果：病灶均位于胃窦部，最大径1．8—3．2cm，平均2．5cm，病灶密度均匀或不均匀，未见出血、坏死及囊变。增强后动脉期呈明显均匀或不均匀强化，门脉期呈均匀强化，与腹主动脉强化曲线一致；肿瘤均可见供血动脉及引流静脉。结论：胃血管球瘤虽然相对少见，但其具有血管性病变及供血动静脉伴行的影像学特点．CT动态增强对本病具有较高的诊断价值。

Objective： To access the accuracy of CT in the diagnosis of gastric glomus and to discuss its value by reviewing the literature. Methods： A retrospective analysis of the CT characteristics of gastric glomus （such as tumor size, CT value, enhancement mode, feeding artery and draining vein, and so on） was done. The study included 5 cases of gastric glomus confirmed by surgery and pathology （3 females and 2 males, age range 49-72 years old, average age was 61 years old）. Dynamic enhanced CT scanning and MPR was used. Results： All the lesions located in the gastric antrum （5 cases）, with the diameter ranging from 1.8 to 3.2 cm, and the average size was 2.5 cm. The density of the lesions was uniform or not, without hemorrhage, necrosis or cystic changes. The enhancement of the tumors in arterial phase was obviously homogeneous or not, and they were homogeneously enhanced in portal vein phase, similar with the enhancement of the abdominal aorta. Also, feeding artery and draining vein were found in tumors. Conclusions： Although the gastric glomus tumor is relatively rare, it has certain imaging characteristics of vascular disease, with feeding arteries and companying veins. Dynamic enhanced CT has a high value in the diagnosis of the disease.
