ObjectiveTo summarize the clinical and imaging features of hepatic adrenal rest tumor and to explore its tissue source, diagnosis, differential diagnosis and treatment.MethodsThe clinical data of patient with hepatic adrenal rest tumor in the West China Hospital of Sichuan University were analyzed retrospectively. The diagnostic methods of liver adrenal junction were summarized by consulting relevant literatures.ResultsThe patient was admitted to the hospital with right hepatic lesions. The preoperative imaging examination showed that it was the imaging features of hepatocellular carcinoma. The right hemihepatectomy was proposed. During the operation, it was found that the lesions were not from the liver, but from the retroperitoneum (The possibility of adrenal origin was very high). Then, the retroperitoneal occupying lesions was completely resected via urology surgery consultation. The pathological results showed that the tumor was adrenocortical carcinoma.ConclusionsIt is very difficult to accurately diagnose nature of hepatic adrenal rest tumor before operation only by results of cross-sectional imaging, especially for some adrenal tumor. It needs to fully be evaluated and even to perform multidisciplinary discussion if necessary for patients who have hepatic adrenal rest tumor before operation, so as to avoid misdiagnosis to a certain extent.
