Cavitary Metastases from Esophageal Carcinoma
General Considerations
- Metastases to the lung occur in about 30% of all malignant disease
- Routes of spread include hematogenous, lymphangitic and direct extension
- Most metastatic lung nodules develop through hematogenous spread
- Primary lung carcinomas cavitate more frequently than metastatic lesions to the lung
- Most cavitary metastases are epithelial in origin
