Abstract

CONTEXT: Computed tomography (CT) unenhanced attenuation value of <10 Hounsfield units (HU) has an excellent specificity (98%) to diagnose lipid-rich adrenocortical adenomas (ACAs) with a weaker sensitivity (71%).
OBJECTIVE: To determine from a routine clinical perspective if unenhanced attenuation value is influenced by cortisol secretion in ACAs.
DESIGN: This was a retrospective study of cases collected between 2009 and 2012.
SETTING: This study was conducted in a tertiary-care university hospital. PATIENTS: Seventy-two patients operated on for an ACA (Weiss score ≤ 2) were analysed. Thirty-four patients had an ACA oversecreting cortisol (Cush-ACA). Thirty-eight patients had an ACA without cortisol oversecretion (Non Hyper-ACA). MAIN OUTCOME MEASURE: CT unenhanced attenuation value was correlated with the functional status. The Weiss score items were analysed.
RESULTS: Among the 34 patients with a Cush-ACA a minority (n = 7) had an unenhanced attenuation value under 10 HU. Among the high precontrast density (> 10 HU) Cush-ACAs, washout analysis after contrast administration was consistent with the benign nature of the tumor in ∼ 60% of the cases. Less than 25% clear cells (lipid-rich cells), a Weiss score item, was present in 50% of the Cush-ACAs in favour of a lipid-poor content.
CONCLUSIONS: Unenhanced attenuation value has a poor sensitivity to diagnose an ACA in case of cortisol oversecretion due to poor lipid content. Nevertheless, the accuracy of washout analysis was preserved in the group of Cush-ACAs.
