Adrenohepatic fusion (AHF) is a union of the right adrenal gland and the liver with intermingling of parenchymal adrenal and liver cells. The phenomenon can be of clinical importance when evaluating patients with adrenal tumors. Using conventional imaging techniques such as computed tomography, a benign adrenal adenoma developing in an adrenohepatic fusion may mimic an invasive hepatocellular carcinoma or adrenal cortical carcinoma. This study presents a comprehensive review of the literature and shows a prevalence of 5.6 percent in autopsy studies. Moreover, 19 patients with adrenal masses in AHF are presented together with their clinical data.
