Why the study?
Primary pulmonary angiosarcomas are rare, and diagnosis is frequently delayed because insidious clinical symptoms and imaging findings mimic pulmonary thromboembolism.
Primary pulmonary angiosarcoma can mimic pulmonary thromboembolism on imaging and should be suspected when a filling defect progresses despite adequate anticoagulant therapy.
Primary pulmonary angiosarcomas (PPAs) are rare, and often, their diagnosis is delayed because of insidious clinical symptoms and imaging findings mimicking pulmonary thromboembolism (PE). A 33-year-old female patient presented with chest pain and progressive dyspnoea. Her initial diagnosis, based on clinical symptoms and CT pulmonary angiography (PA) findings, was PE. However, after treatment with anticoagulants, the patient failed to improve. A follow-up CTPA and further CT-guided biopsy results were compatible with angiosarcoma.
