Patient Data :

Age : 41 - Gender : Female

Diagnosis :

Alveolar echinococcosis of the liver

Findings :

Axial unenhanced T1 and T2-weighted MR images show an infiltrating mass in the right lobe of liver. The mass has a low signal intensity compared to the liver parenchyma on T2WI. Axial T1W MR images after administration of intravenous contrast medium show no arterial phase enhancement within the mass and only faint enhancement of peripheral fibroinflammatory components in the portal venous and late venous phase.

History :

A patient with several episodes of epigastric pain, liver enzyme abnormality was admitted to the hospital. A liver mass was detected on ultrasound imaging.
Show my name ?

My favorite diagnosis is peripheral colangiocarcinoma, because the mass shows heterogeneous peripheral enhancement and seems hipointenes on T2WI due to fibrotic content.

mass is hipointense on T1WI and T2WI . hypointense rim within probably related to calcification and peripherally irregular enhancement on postcontrast images. I think it seems like alveolar echinococcus but i'm not totally sure about the enhancement pattern.

Maybe it is an ischemia with acute and subacute bleeding...

am I the only one who thinks of alveolar type hepatic hydatid infection?

Gulten unless you read other comments; you can always be the only one who thinks alveolar infection :)
