Cirrhosis: an unusual pattern of enhancement on CT.

A previously unreported pattern of enhancement of the liver on CT in a 7-month-old female with cirrhosis is illustrated. Precontrast scans showed the liver to have a normal homogeneous density throughout. Scans performed immediately after rapid bolus injection of contrast showed an uneven enhancement of the entire liver. Bands of enhancing tissue (thought to represent vascular fibrous tissue) surrounded more extensive areas that enhanced less markedly. Delayed post-injection scans revealed again an even level of density throughout the liver.
