Summary Objective To evaluate volumetric and densitometric properties of the adrenal glands in patients with unilateral and bilateral disease in comparison with normal controls. Design A total of 77 patients (56 males and 21 females) diagnosed with primary aldosteronism ( PA ) with a mean age of 53 ± 10 years were prospectively enrolled. Unenhanced and contrast‐enhanced computed tomography scans were analysed for adrenal volumes and mean densities. These values were compared with normal controls and between PA subtypes. Results Adrenals containing an aldosterone‐producing adenoma ( APA , n = 56) had on average higher attenuation values as compared to adrenals with bilateral adrenal hyperplasia ( n = 21). Mean adrenal gland volume in PA patients was not significantly different between PA subtypes. In comparison with normal adrenal glands, volumes were significantly higher in PA patients ( P < 0·0001) including adrenals contralateral to APA s, which were significantly larger in comparison with controls. Conclusion Independent of subtype differentiation, adrenal volumetry reveals higher adrenal volumes in PA patients in comparison with normal controls. These findings provide indirect evidence for a general adrenal growth dysregulation in the context of PA .
