Angiosarcoma, a rare cancer, often presents as a hypervascular mass on CT and angiography, sometimes with bone defects. These aggressive tumors can deceptively appear benign initially.

Area of Science:

  • Oncology
  • Radiology
  • Pathology

Background:

  • Angiosarcoma is a rare and aggressive malignant vascular tumor.
  • Its diverse primary sites lead to varied imaging presentations.
  • Understanding imaging findings is crucial for early diagnosis.

Purpose of the Study:

  • To review the imaging findings and clinical behavior of angiosarcoma.
  • To identify common radiographic, computed tomography (CT), and angiographic features.
  • To correlate imaging findings with clinical presentation.

Main Methods:

  • Retrospective review of 30 angiosarcoma cases.
  • Analysis of radiography, computed tomography (CT), and angiography findings.
  • Review of clinical course and presentation.

Main Results:

  • The most common finding was a hypervascular soft tissue mass on CT and angiography.
  • Well-demarcated cortical defects in long bones were frequently observed.
  • Angiosarcomas exhibited a deceptively benign clinical presentation.

Conclusions:

  • Angiosarcoma imaging is characterized by hypervascular masses and potential bone involvement.
  • The aggressive nature of angiosarcoma can be masked by a benign clinical appearance.
  • Multimodality imaging is essential for diagnosing angiosarcoma.
