Hepatic adrenal rest tumour
A hepatic adrenal rest tumour (HART) (previously been termed primary hypernephroma of the liver or hypernephroid carcinoma of the liver) is a very rare liver tumour with histology similar to adrenocortical carcinoma
It tends to occur in younger patients and there is no regosnised genders predilection.
It is considered to be derived from the adrenal rest in the liver. The presence of fat within the tumour is the most characteristic feature.
While imaging features a non specific it usually appears as a round, well defined mass in the liver. There may be a right lobe predilection. Lesions are typically subcapsular and can demonstratinghypervascularity. They can often contain foci of calcification.
One specific radiological imaging feature is the presence of fat components.
