Case Discussion
Simple case of consolidation with cavitation, in this case secondary to primary lung cancer in a smoker.
Differential diagnosis for a cavitating lung lesion is the mnemonic CAVITY:
-
C: cancer
- bronchogenic carcinoma: most frequently SCC
- cavitatory pulmonary metastasis(es): again most frequently SCC
-
A: autoimmune; granulomas from
- Wegener's granulomatosis
- rheumatoid arthritis (rheumatoid nodules) etc.
- V: vascular (both bland and septic pulmonary embolus)
- I: infection (bacterial/fungal)
- T: trauma - pneumatocoeles
- Y: youth
