Abdominal ultrasonography in hepatolenticular degeneration. A study of 33 patients

The ultrasonographic study of 33 patients with hepatolenticular degeneration showed the following main changes: disorders of the hepatic echotexture (29 cases), changes of the splenic dimensions (21), liver shrinkage (10), cholelithiasis (8), hepatomegaly and ascites (1). The disorders of liver echotexture exhibited different patterns, from slight to severe changes of the hepatic echogenicity, associated with anatomic distortions of the liver, such as alterations of outline and decrease of dimensions. Liver shrinkage was always accompanied by splenomegaly. The scarcity of hepatomegaly may be explained by the fact that the ultrasonography was performed after the onset of treatment with penicillamine, or by other factors still unknown, copper perhaps possessing a stronger fibrogenetic action than other hepatotoxic agents. Cholelithiasis was very frequent in females (6 of 13 patients), its incidence tending to increase with age. Regarding males there was no increase when the incidence was compared to the general population. The two sole males were young, an unusual finding in normal men.
