Imaging findings
A soft tissue lesion in the left upper lobe has an irregular margin, abuts the hilum, and extends along the bronchovascular bundle. Other nodules are present in the lungs, and the patient has a history of mastectomy.
Key takeaways
This is a biopsy-proven case of metastatic breast cancer. The metastasis is presumably spreading along the bronchovascular bundle or lymphatics, secondarily involving the airways, or presenting as a primary bronchial metastasis. Its appearance, extending along the bronchovascular bundle, can mimic a primary lung cancer with associated obstruction.
