Angiosarcoma is an uncommon malignant vascular tumor accounting for less than 1% of all malignancies. Though angiosarcoma can occur in any region of the body, head and neck skin lesions are often seen in elderly persons. And cutaneous angiosarcoma is high grade aggressive tumors that tends to recur locally and metastasize. In this presentation, we will present the imaging features of angiosarcomas that occurred in skin, heart, breast, liver, and so on. We are going to describe 1) the clinical features of angiosarcoma, 2) the imaging findings of angiosarcoma on CT, MRI and FDG-PET, and 3) the differential diagnosis. This knowledge will be helpful to understand this disease and imaging features for prompt and accurate diagnosis.

We are going to present the following: 1. Clinical features of angiosarcoma in each organ: soft tissue (skin, muscle), liver, heart, breast, lung, etc. 2. CT and MRI findings (signal intensity, contrast enhancement) 3. FDG-PET/CT 4. Pathological findings 5. Differential diagnosis
