Primary angiosarcoma of the abdominal aorta: multi-row computed tomography

Area of Science:

• Vascular Surgery
• Diagnostic Imaging
• Oncology

Background:

• Primary angiosarcoma of the aorta is an exceptionally rare malignancy.
• Symptoms often mimic common atherosclerotic occlusive disease, delaying diagnosis.
• Histopathological confirmation is typically post-surgical reconstruction.

Observation:

• This report details interventional and CT-angiographic findings in a 71-year-old patient.
• A polyploid intimal alteration within the abdominal aorta was visualized.
• Segmental obstruction of the aortic lumen was noted without significant atherosclerotic changes.

Findings:

• CT angiography demonstrated distinct intimal alterations.
• The observed morphology suggested an intravascular malignancy rather than atherosclerosis.
• Non-atherosclerotic segmental aortic obstruction is a key diagnostic clue.

Implications:

• CT angiography can aid in the early diagnosis of aortic angiosarcoma.
• Recognizing specific imaging features can guide differential diagnosis.
• Prompt identification of intravascular malignancy is crucial for timely intervention.
