Aneurism of the left portal vein branch in a teenager - a rare clinical case

The authors presented their own clinical observation of an aneurysm of the left portal vein branch in a teenager with a long-term asymptomatic course. Reduced serum concentrations of ceruloplasmin and α-1-antitrpsin made diagnostic search difficult, which could lead to incorrect therapeutic decisions. However, the results of imaging methods allowed us to establish the root cause of liver damage and its cirrhotic transformation. Vascular aneurysms of the portal vein system are a very rare pathology, and it should be taken into account in the differential diagnostic algorithm while excluding other, more obvious causes of liver pathology.
