Learning objectives

To show atypical radiological manifestations of thoracic metastasis based on histopathological origin, metastatic mechanism and after administration of treatment.

Background

Pulmonary metastasis are seen in 20-54% of extrathoracic malignancies. Lungs are the second most frequent site of metastases from extrathoracic malignancies. Twenty percent of metastatic disease is isolated to the lungs.The common tumours which metastasise to the lung include renal, breast, colon, and prostate carcinomas, as well as sarcomas. The development of pulmonary metastases in patients with known malignancies indicates disseminated disease and places the patient in stage IV in TNM (tumor, node metastasis) staging systems. This typically implies an adverse prognosis and alters the...

Conclusion

It is not uncommon to find thoracic metastasis with atypical radiological manifestations. It is important to know these unusual radiological presentations to distinguish them from other non-malignant lung diseases.
