摘要
目的:提高腹膜后椎前副神经节瘤的CT诊断水平。方法:报道3例经手术病理证实的腹膜后椎前副神经节瘤的临床资料、CT表现、病理结果并复习相关文献。结果:3例患者均位于腹膜后椎前、腹主动脉右侧、右侧肾上腺前内方。动脉期病灶实性部分呈中等程度不均匀强化;门脉期强化更广、更均匀;延迟期病灶强化程度开始减低;坏死区不强化,于门脉期边界显示最清。2例患者手术完全切除,1例部分切除,随访一年患者基本情况良好。结论:CT检查尤其是双期扫描并结合临床可提高诊断率,并为手术提供相关资料。
Objective： To improve the CT level of diagnosis for retroperitoneal prevertebral paraganglioma. Methods： Clinical data and CT findings of 3 patients with retroperitoneal prevertebral paraganglioma confirmed by pathology were reported and the literature was reviewed. Results： Three tumors all located among retroperitoneal prevertebral area, the right of abdominal aorta and the anterior part of right adrenal. In arterial phase, the parenchymal lesion was moderately and inhomogeneously enhanced; in portal-venous phase, it was enhanced more widely and homogeneously; in delay phase, the CT value of solid lesion descended; The necrosis part was not enhanced but manifested best in portal-venous phase. Three patients all underwent surgical resection, with tumors removed completely in 2 cases and partly in one case. Three patients were still alive at the follow-up of one year. Conclusions： CT scan, especially the double phase enhanced scan, combining with clinical information are useful for improving accurate diagnosis on the neoplasm.
