    <valueString value="The examination demonstrates a well circumscribed 3 cm lesion present within the medial aspect of the inferior right liver lobe. Initial evaluation demonstrates lack of contrast enhancement. Subsequent imaging (not shown) demonstrated typical contrast enhancement pattern of a benign hemangioma of the liver. The remaining contrast enhancement pattern in the liver is normal. There is normal appearance of the adrenal glands, spleen, kidneys, and pancreas. There is no evidence of liver metastasis." />
