“…From the radiographic respect, the hepatic tumors in this case appeared as hypoattenuating masses with heterogeneous enhancement on contrast‐enhanced CT. Although these CT findings are considered to be non‐specific and do not aid in distinguishing the tumors from other metastatic hepatic tumors, these radiologic findings were consistent with previous descriptions of primary or metastatic angiosarcoma of the liver …”

Hepatic angiosarcoma is a very rare disease, accounting for only 2% of primary liver malignancy. An 82-year-old man was admitted to our hospital because of jaundice and weight loss. Computed tomography (CT) and magnetic resonance imaging (MRI) showed diffuse and multiple space-occupying lesions. On gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced MRI, the tumor was not enhanced intensely in the arterial phase following contrast injection, and was then gradually enhanced homogeneously. In the delayed phase and hepatobiliary phase, the tumor was completely washed out. Whole-body (18) F-fluorodeoxyglucose positron emission tomography (FDG-PET)/CT fusion scanning confirmed metabolic activity with maximum uptake value of 3.64 in the lesions. A liver biopsy showed spindle-shaped tumor cells proliferating along sinusoids, with elongated and hyperchromatic nuclei. Immunohistochemical studies showed tumor cells positive for von Willebrand factor and CD34. These findings were consistent with angiosarcoma of the liver. This case report is the first description of co-registered FDG-PET/CT images and Gd-EOB-DTPA-enhanced MRI of primary hepatic angiosarcoma.

“…3 underwent an ultrasonography‐guided liver biopsy, which revealed liver cirrhosis and necrosis only. A pathological examination has been proven to be the best approach for confirming primary hepatic angiosarcoma 16,17 . Its microscopic features are characterized by the proliferation of single or multilayered tumor cells along the sinusoids, the atrophy of liver cell cords and a solid tumor nest composed of spindle‐shaped and polyhedral cells without significant vascular spaces 18 .…”

Angiosarcoma is a rare, aggressive subtype of soft-tissue sarcoma with a propensity for local recurrence and metastasis associated with a generally poor prognosis, unless diagnosed early. Given the vascular endothelial cell origin of angiosarcoma, tumours may develop in essentially any organ; however, there is a predilection for the skin where half of all tumours arise, increasing in prevalence with age. The most common risk factors are chronic lymphoedema and history of radiation. We review the most important radiological findings along the spectrum of angiosarcoma from head to toe throughout the body, including uncommon and rare locations. Key imaging features of angiosarcoma across multiple organ systems will be described, as well as the impact on management and prognosis.

Hepatic metastases of soft tissue angiosarcoma: CT and MR imaging findings

Abstract: The common CT findings of metastatic angiosarcoma in our series were multiple hypoattenuating lesions often associated with nodular enhancement and cystic lesions with hemorrhagic change.
