Cavitating pulmonary metastases refer to pulmonary metastases which then tend to cavitate. The term is similar but may not be identical to cystic pulmonary metastases in which the wall of the former may be thicker.

Epidemiology
Cavitation is thought to occur in around 4% of lung metastases 2.
Pathology
Cavitary pulmonary metastases can come from the following primaries:
squamous cell carcinoma (70%): lung or head and neck primary 1,4,6
adenocarcinoma: gastrointestinal tract, breast 4,6
sarcoma 4
pancreatic adenocarcinoma: very rare 8
Cavitating pulmonary metastases have also been reported to develop after chemotherapy, thought to be secondary to tumor necrosis or a valve-effect on an adjacent bronchus 4,5.
Treatment and prognosis
Complications
One particular complication that can occur includes the formation of a pneumothorax or a hemopneumothorax.
Differential diagnosis
For multiple cavitating lung lesions (nodules or masses) on imaging consider:
necrobiotic lung nodules: rare
pulmonary tuberculosis: upper lobe predominant consolidative region with cavitation
