CT Scan abdomen on Epithelioid hemangioendothelioma

ct scan abdomen On unenhanced CT images, the nodular type of EHE is of low attenuation, corresponding to myxoid stroma. After intravenous administration of contrast material, areas of high density can be observed in the periphery of the tumor, however, the center of the tumor shows very few or no contrastenhancing areas.

In the ct scan abdomen diffuse type of EHE, CT scans reveal large, hypodense, diffuse areas throughout the liver extending toward the periphery. The outline is usually irregularly shaped. Focal calcifications within the tumor are found in about 20% of cases.

Compensatory hypertrophy of unaffected liver segments, as well as splenomegaly, are common findings. The ct scan abdomen liver capsule is not usually affected, although confluent nodules may produce capsular retraction.


Epithelioid hemangioendothelioma on CT. Unenhanced Cct scan abdoemen a) reveals large hypodense, confluent diffuse nodules (asterisks). Arterial (b) and portal-venous (c) phase images acquired after the administration of contrast material reveal enhancement at the periphery of the nodules but few contrast-enhancing areas at the center of the lesions. In the equilibrium phase (d) the nodules become heterogeneously hyperdense compared to normal liver, while compensatory hypertrophy and capsular retraction can be clearly seen.
