ABSTRACT
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.

OBJECTIVE: The purpose of this article is to review the use of dual-energy CT (DECT) in the assessment of gynecologic cancer. CONCLUSION: DECT has the potential to improve diagnostic performance, may improve the ability to differentiate between simple cystic lesions and primary ovarian cancer, and may also improve the detection of musculoskeletal and liver metastases. Additional studies will be needed to determine the direction of future developments and the degree to which DECT will affect the imaging and management of gynecologic cancer.
