Adrenal cortical adenoma in adrenohepatic fusion tissue: a mimic of malignant hepatic tumor at CT

Abstract

Adrenohepatic fusion is defined as adhesion of the liver and right adrenal cortex and close intermingling of the respective parenchymal cells [1], with partial or complete absence of the fibrous capsule dividing the two organs [2]. Although it is not rare at autopsy [1], the clinical significance of adrenohepatic fusion has been rarely described. We report a case of adrenal cortical adenoma that developed in adrenohepatic fusion tissue and mimicked malignant hepatic tumor at CT and angiography- assisted CT.
