Abstract:
ObjectiveTo 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.ResultsThe 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.
