Biopsy was taken from the hepatic focal lesions revealed epithelioid hemangioendothelioma.
Epithelioid hemangioendothelioma (EHE) is a rare relatively low-intermediate grade malignant vascular tumor. It occurs around medium to large venous structures.
It can occur in a number of sites
In hepatic epithelioid hemangioendothelioma, focal lesions are usually hypoattenuating, showing marginal (target/halo pattern) contrast enhancement. They may show internal calcifications or cause capsular retraction. The lesions are usually marginally located.
In pulmonary epithelioid hemangioendothelioma, the pulmonary nodules are usually small and multiple, with random distribution as in this case. Calcifications are occasionally seen within the nodules.
