    目的 探讨ACTH非依赖性大结节样肾上腺增生(AIMAH)的多层螺旋CT特征性表现.方法 回顾性分析24例(男性14例,女性10例)经临床证实的AIMAH患者的多层螺旋CT形态学表现和强化方式.结果 24例患者均为双侧肾上腺受累(100％),双侧肾上腺明显增大,伴多个大小不等结节,结节大小约为0.50 ～3.85 cm[平均(1.79:±1.02) cm],正常肾上腺组织被扭曲,结节之间的肾上腺肢体亦可明显增粗,增大的肾上腺保持原有的轮廓,呈特征性“生姜样”改变.22例(91.7％)增生的肾上腺呈均匀轻度强化.仅1例出现有钙化.结论 多层螺旋CT能很好地显示肾上腺病灶的形态学改变和强化特点,同时结合临床表现和生化指标,可明显提高检出AIMAH的敏感性和准确性.

    Objective To explore the characteristics multi-detector-row computed tomography (MDCT)findings of ACTH-independent macronodular adrenal hyperplasia ( AIMAH ).Methods The un-enhanced and contrast-enhanced MDCT features in 24 patients ( 14 males and 10 females) with clinically confirmed AIMAH were retrospectively assessed for the morphology and enhancement patterns.Results The adrenal glands were involved bilaterally in all of the 24 cases( 100％ ).24 patients had massively enlarged multinodular adrenal glands.Nodules were( 1.79 ± 1.02) cm (0.50 ～ 3.85 cm),which usually distorted and completely obscured the normal adrenal glands.The enlarged adrenal glands were still retained the adreniform contour,showed characteristic "ginger-like".22 of the 24 ( 91.7 ％ ) hyperplastic nodular glands demonstrated mild homogeneous enhancement.Calcification was revealed in 1 adrenals ( 1/24,4.2％ ).Conclusion MDCT reveals the characteristic morphology and CT attenuation in AIMAH.Combined with its clinical presentation and biochemical findings,AIMAH is able to be diagnosed with high specificity and accuracy on MDCT.
