Summary
Pulmonary tumor emboli are rare but should be considered in patients with a history of cancer. Look for enlarged pulmonary arteries and enhanced thrombus on scans.
Area of Science:
- Oncology
- Radiology
- Pathology
Background:
- Pulmonary tumor emboli (PTE) are uncommon occurrences in clinical practice.
- Malignancies can metastasize to the lungs through vascular channels.
- Early recognition of PTE is crucial for patient management.
Observation:
- Two cases of PTE are presented.
- Case 1: A patient with chondroblastic osteosarcoma of the pelvis.
- Case 2: A patient with testicular seminoma.
Findings:
- Pulmonary arteries may enlarge in patients with PTE.
- Delayed scan enhancement of thrombus is a key radiological finding.
- PTE can arise from diverse primary tumor types.
Implications:
- Consider PTE in patients with a history of malignancy presenting with pulmonary artery enlargement.
- Advanced imaging techniques, including delayed scans, aid in PTE diagnosis.
- This finding underscores the importance of a comprehensive differential diagnosis in oncology.
