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 diagnosis of retroperitoneal paraganglia. Methods: The clinical data, CT findings and pathological findings of 3 cases of retroperitoneal paraspinal ganglia tumor confirmed by surgery and pathology were reviewed. Results: All three patients were located in the anterior posterior vertebral body, right aorta and right anterior adrenal. The solid part of the arterial phase was moderately uneven enhancement; the portal phase was more extensive and more uniform; the degree of enhancement of the lesion began to decrease; the necrotic area was not enhanced and the portal phase was the clearest. Two patients underwent complete resection and one was partially resected. The patients were basically well-off one year after follow-up. Conclusion: CT examination, especially double-phase scanning combined with clinical diagnosis can improve the rate and provide relevant information for surgery.
