目的：调查分析胃血管球瘤的CT表现及临床特征。方法：回顾性分析经手术和病理证实的７例胃血管球瘤病例的临床资料及CT影像学表现，观察肿瘤的生长位置、大小、数目、形态、生长方式、表面胃黏膜和周围胃壁情况，测量病灶各期的CT值及分析强化趋势和特点。结果：病灶位于胃窦部6例，位于胃窦与胃大弯交界处1例，均单发，大小均在3 cm以内，腔内生长6例，腔内外混合生长1例。肿瘤平扫密度均匀，均未见出血、坏死及囊变，仅1例出现钙化。增强后，5例动脉期表现为肿瘤周边部轻度絮片状强化，其中1例可见粗大紊乱血管显影，门静脉期均匀显著强化达到峰值，CT值分别为139.25 HU、132.42 HU、146.53 HU、140.36 HU、135.16 HU，延迟期持续强化；2例动脉期表现为均匀显著强化达到峰值分别为138.67 HU、148.36 HU，门脉期呈持续均匀强化，延迟期仍持续强化，但程度较前两期减弱，7例胃壁黏膜光整，均不伴远处及淋巴结转移。结论：胃血管球瘤多发生于中老年女性，胃窦部多见；肿块位于黏膜下，密度均匀，有时可见钙化；动态增强扫描根据病理亚型表现不同强化趋势，呈明显均匀强化，强化峰值与腹主动脉相近的强化特征。

Objective: To investgate and analyse the clinical characteristics and the CT imaging features of the gastric glomus tumors. Methods: Clinical characteristics and the imaging features of seven cases proved pathologically were analyzed retrospectively. The location, size, quantity, shape, margin, growth pattern, gastric mucosa, and the adjacent gastric wall were evaluated. The CT values of each period after enhancement were detected. Results: The lesions of six cases were distributed in gastric antrum and one case was in the junction of gastric antrum and greater curvature, with the size within 3 cm. Six cases were internal cavity growth and one internal and external cavity mixed growth. All cases manifested homogeneous density in CT plain scan, without hemorrhage, necrosis and cystic degeneration, calcification was found in one case. Five cases showed peripheral patched shaped enhancement in arterial phase, 1 case showed gross disordered vessel inside the tumor. A significant enhancement reached the peak in portal vein phase, CT values were 139.25 HU, 132.42 HU, 146.53 HU, 140.36 HU, 135.16 HU respectively, and continued to strengthen in the delay phase. Two cases reached enhancement peak in arterial phase were 138.67 HU and 148.36 HU, continuously and homogeneously enhanced in the portal vein phase but weakened in delay phase. All cases were without distance and lymphnodes metastasis. Conclusion: Gastric glomus toumor has a specific pathogenetic location and age of onset, typically presents as a benign and hypervascular tumor with a obvious and homogeneous enhancement pattern. The peak CT value of enhancement is similar to the abdominal aorta.
