摘要
目的 :分析并总结活动性结核所致艾迪生病(Addisondisease)的肾上腺CT表现。材料和方法 :分析18例经手术或随访证实的结核所致艾迪生病肾上腺CT表现。结果 :本组活动性结核所致艾迪生病双侧肾上腺均受累 ,35个活动性结核肾上腺增大 ,1个非活动性结核肾上腺萎缩并钙化。34个(17例)增大的肾上腺造影剂增强后内见坏死区 ,其中19个肾上腺显示中央大片坏死及周边环状增强。35个增大的肾上腺中 ,25个保持其原有轮廓 ,其余10个肾上腺失去原有轮廓而显示为肿块样。7个活动性结核(4例)肾上腺内见小点状钙化。结论 :肾上腺活动性结核引起艾迪生病时CT表现为肾上腺增大伴大片坏死 ,可有点状钙化。增大的肾上腺常保持其原有轮廓 ,但小部分亦可表现为肿块样。艾迪生病患者的肾上腺CT检查对区分病因、判断结核病变期别有重要意义。
Purpose: To identify the CT findings of Addison disease caused by adrenal tuberculosis(Tb).Materials and Methods: The adrenal CT appearances in 18 cases verified by operation or long term follow-up with Addison disease caused by Tb were analyzed. Results: Both bilateral adrenal glands were involved in all 18 cases. Thirty five glands with active Tb appeared as adrenal glands enlargement and one adrenal gland with old Tb appeared as adrenal atrophy with calcification. A nonenhancing necrotic area within an enlarged adrenal gland was seen in 34 glands(17 cases), among them 19 glands presented the peripheral rim enhancement. In 25 of the 35 enlarged glands their contours were kept normal, the remaining 10 glands lost their normal contours. Small calcification dots in the adrenal gland were seen in 7 glands with active tuberculosis(4 cases). Conclustion: The CT manifestations of active adrenal Tb associated with Addison disease are adrenal glands enlargement with large necrotic areas, with or without calcification dots. While the normal contours of adrenal gland are demonstrated, the diagnosis of infectious disease can be made with increased confidence. Adrenal Tb should not be excluded when the enlarged adrenal gland appears as a mass lesion. The CT manifestations may help to elucidate the etiology of Addison disease caused by adrenal Tb and may also help to stage the Tb.
