Pseudotumours of hepatic imaging.
The diagnosis of liver tumours with CT depends on differential attenuation coefficients and enhancement patterns. The sensitivity of CT in defining tumours is well established but there remain a variety of conditions that mimic these patterns, presenting a 'pseudotumour' appearance. A common illustrative example is hepatic steatosis, but less well recorded are the sphingolipidoses and intrahepatic arterioportal shunts, either post-traumatic or related to venous outflow block. Alpha-1-antitrypsin deficiency and hereditary tyrosinaemia provide examples in childhood.
