We present a case of an incidentally detected cystic liver mass on CT scan, with histology showing biliary epithelium embedded in fibrous stroma and dysplastic features, consistent with an adenofibroma. This is only the third case described in the literature with malignant histology and the first case with angiographic imaging and subsequent management with preoperative embolization prior to surgical resection. We discuss the differential of the imaging findings and the features of this rare entity. Because of the risk of malignant transformation, consideration of this tumour is important to ensure early detection and ultimately resection for improved survival.
