Summary
A rare angiosarcoma case presented as a stroke due to carotid artery thrombus. Definitive origin and optimal treatment remain challenging due to unclear pathology and embolization source.
Area of Science:
- Vascular Surgery
- Neurology
- Oncology
Background:
- Angiosarcoma is a rare vascular endothelial malignancy.
- This case presents angiosarcoma manifesting as thromboembolic stroke.
- Literature review and management challenges are discussed.
Observation:
- A 77-year-old man experienced recurrent transient ischemic attacks and stroke.
- Carotid endarterectomy revealed friable thrombus with angiosarcoma.
- No extraluminal or proximal tumor source was identified.
Findings:
- Histopathology confirmed angiosarcoma within the carotid artery thrombus.
- The precise origin of the angiosarcoma remains undetermined.
- Optimal therapeutic strategies are difficult to define.
Implications:
- Highlights a rare presentation of angiosarcoma.
- Underscores diagnostic and therapeutic challenges in similar cases.
- Suggests the need for further research into angiosarcoma management.
