Patient Data
Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.
There is a large filling defect involving the left main pulmonary artery and extending into all branches. The mass is also extending outside the vessels wall into adjacent lung parenchyma, imaging findings are suggestive of pulmonary angiosarcoma. However, the possibility of chronic pulmonary thromboembolism can not be ruled out completely on the basis of images.
Case Discussion
CT images demonstrate pulmonary angiosarcoma; however chronic pulmonary thromboembolism can mimic the features of angiosarcoma to differentiate between two entities further evaluation with FDG-PET or biopsy is required.
