Abstract：Objective To analyze and summarize the clinical and radiological characteristics of 3 patients with ectopic adrenal adenoma in liver,in order to improve the understanding of this disease.Methods The data of 3 patients with hepatic ectopic adrenal adenoma confirmed by pathology were retrospectively analyzed,and relevant literatures were reviewed.Results The lesions of 3 cases were all located in segment Ⅶ,subcapsular to the right lobe of the liver,and presented as solitary nodules.CT showed round or oval hypodense masses.MRI showed slightly hypointense on T1WI in-phase,significantly decreased signal on out-of-phase,slightly hyperintense on T2WI,and restricted diffusion on DWI.On enhanced MRI scans,the lesions showed marked heterogeneous enhancement in the arterial phase,and relative hypoattenuation in the portal venous and delayed phases,presenting a"wash-in,wash-out"pattern.One case showed capsular enhancement in the delayed phase.All three cases showed intracellular steatosis.Conclusions Ectopic adrenal adenoma of the liver has distinct clinical manifestations,locations,and imaging features.A combination of clinical and imaging findings is helpful for the diagnosis of this disease.
