目的探讨胃血管球瘤的CT特征。方法回顾性分析8例经手术病理学检查确诊的胃血管球瘤患者的CT表现,并与病理学检查结果进行对照分析。结果 7例患者肿瘤单发,胃窦部5例,胃体部2例;肿瘤大小11~37 mm,平均24 mm,呈圆形、类圆形或不规则形,边界清晰;腔内生长4例,腔外生长1例,混合性生长2例;CT平扫肿瘤呈均匀性等高密度,动脉期明显强化,静脉期均进一步强化,术后病理学检查证实单发者均为良性胃血管球瘤。1例患者胃体、胃窦及小肠内见多发病灶;肿瘤CT平扫可见分叶、囊变、溃疡,增强后动脉期不均匀强化,静脉期进一步强化;病理学检查确诊为恶性胃血管球瘤,肾上腺、脾脏及两肺内多发转移灶。结论胃血管球瘤好发于胃窦部、女性多见,体积偏小,呈圆形、类圆形或不规则形,边缘清晰;增强CT检查示动脉期肿瘤明显强化,静脉期进一步强化;肿瘤多发者提示恶性可能。
Objective To investigate the CT features of gastric glomus tumors. Methods The CT appearances of 8 cases of gastric glomus tumor diagnosed by surgical pathology were retrospectively analyzed and compared with the results of pathological examination. Results Seven patients had single tumors, 5 cases of gastric antrum and 2 cases of stomach body. The tumor size was 11-37 mm with an average of 24 mm. It was round, round or irregular, with clear boundaries; Cases, extraluminal growth in 1 case, mixed growth in 2 cases; CT plain tumors showed high homogeneity, high density, arterial phase was significantly enhanced, venous phase were further strengthened, postoperative pathological examination confirmed that the single were benign gastric vessels Ball tumor. One patient had multiple lesions in the corpus, antrum, and small intestine. Tumor CT scanning showed dissection, cystic degeneration, and ulceration, enhanced arterial phase non-uniform enhancement, and venous phase enhancement; pathological examination confirmed malignant gastric vasculature Tumor, adrenal, spleen, and multiple metastases in both lungs. Conclusion Gastric glomus tumors are predominant in the antrum of gastric antrum, more common in females, smaller in size, round, round or irregular, with clear edges; enhanced CT examination shows that the arterial phase tumors are significantly enhanced and the venous phase is further strengthened; Multiple tumors suggest malignant potential.
