Describe and provide imaging features of various pulmonary arterial and venous tumors. Discuss important clinical implications of these tumors. Discuss the role of Dual Energy CT and Spectral CT in these lesions.
Recognition of pulmonary venous and arterial tumors has an important clinical role in identifying cause of symptomatology,
planning for interventional procedures such as surgery,
and guiding management. Pulmonary arterial and venous tumors may be primary,
or metastatic in the form of tumor emboli. These tumors can be differentiated into benign or malignant etiologies. Benign pulmonary artery tumors includepapillary fibroelastoma,
and leiomyoma. Malignant primary...
Findings and procedure details
Pulmonary venous and arterial tumors must be distinguished from other pulmonary vascular pathology,
and can be aided by the use of Dual Energy and Spectral CT.
Here we review imaging findings of pulmonary arterial and venous tumors: Primary benign pulmonary arterial tumor Papillary fibroelastomas are benign tumors that arise from cardiac valves.
These lesions can be complicated by pulmonary or systemic embolization depending on the primary site.
Treatment of these lesions depend on size,...
Pulmonary arterial and venous tumors are important for the radiologist to identify accurately in order to make definitive diagnoses and help guide clinical management.Casesfrom local invasion ofprimary lung cancers,tumor emboli to the pulmonary arterial system,
and invasion of metastatic lung lesions with invasion into thepulmonary venous vasculature and left atrium were presented.
It is important to also distinguish these findings from other benign etiologies that may mimic tumor emboli.New...
