CT引导下经皮穿刺乙醇消融治疗无功能性肾上腺肿瘤

目的探讨CT引导下经皮无水乙醇消融术(PEI)对无功能性肾上腺偶发瘤的治疗价值。方法21例肾上腺偶发瘤,均为单发病灶。病灶直径均小于5 cm,其中7例病灶直径小于3 cm。采用CT引导下无水乙醇瘤内注射进行治疗,每个病灶治疗次数不少于2次,治疗后1~2个月,行CT平扫和增强扫描,观察肿瘤大小、坏死情况。结果PEI治疗后CT增强扫描复查,13个病灶(包括直径小于3 cm的7个病灶)完全坏死;8个病灶大部分坏死,经过重复治疗,病灶彻底坏死。已随访1~3年,未见肿瘤复发。结论无功能性肾上腺偶发瘤采用CT引导下经皮穿刺乙醇消融疗法治疗疗效确切,创伤小。

CT-guided percutaneous ethanol injection for the treatment of nonfunctional adrenal tumor

Objective To validate the therapeutic effect of CT-guided percutaneous ethanol injection(PEI) for the treatment of nonfunctional accident adrenal tumor.Methods Twenty-one cases of nonfunctional accident adrenal tumor of singular foci were less than 5 cm.The diameters of 7 cases in 21 cases were less than 3 cm.All of them were treated with CT-guided PEI.The times of treatment were more than twice.Size and necrosis of the tumors were examined by plain and enhanced CT scan 1-2 months after PEI.Results Post-PEI enhanced CT scan showed that 13 foci including the 7 foci which diameters less than 3 cm were completely necrotized.Eight foci were necrotized at large,which were completely necrotized after repeated PEI treatment.There was no recurrence of tumor on following-up for 1-3 years.Conclusion CT-guided PEI for nonfunctional accident adrenal tumor is minimally invasive and its therapeutic effect is favorably definite.
