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

Epidemiology

Cavitation is thought to occur in around 4% of lung metastases ².

Pathology

Cavitatory pulmonary metastases are typically caused by squamous cell neoplasms ^1,4.

Other rare reported situation include

transitional cell carcinoma of bladder ³
adenocarcinomas
sarcomas ⁴

Complications

One particular complication that can occur includes formation of a pneumothorax or a haemopneumothorax.

Differential diagnosis

For multiple cavitating lung lesions (nodules or masses) on imaging consider

septic pulmonary emboli
granulomatosis with polyangitis - Wegener's granulomatosis
necrobiotic lung nodules - rare
pulmonary tuberculosis - upper lobe predominant consolidative region with cavitation
