CTICasesIliac artery angiosarcoma
Imaging findings
Chest and pelvic CT and PET/CT show bilateral nodular pleural thickening, bilateral pleural effusions, subpleural pulmonary nodules, and a hypermetabolic, irregular, intraluminal soft tissue mass in the left common iliac artery.
Key takeaways
Primary arterial angiosarcomas are extremely rare, highly aggressive malignant vascular tumors. They frequently present with thromboembolic complications or early distant metastases, and can manifest pulmonarily as bilateral pleural metastases and malignant effusions.
