Diagnosis With Brief Discussion

Diagnosis
Adenocarcinoma with cystic lung to lung metastasis
Radiologic Findings
Chest CT scans show a spiculated mass in the apex of the left lung with multiple small nodular lesions in both lungs. Some of the nodules appear as cavitary or ring-like lesions.
Brief Review
Cavitation of metastatic nodules is not as common as with primary lung carcinoma. The frequency of it is 4%, in contrast to 9% of primary lung carcinomas. Among metastatic nodules associated with cavitation, 70% are metastatic squamous cell carcinoma. The head and neck in males and the genitalia in females are the most common primary organ sites. Cavitation is observed rarely in metastatic adenocarcinoma, particularly that from colon cancer. Metastatic sarcoma can also be accompanied by cavitation, and pneumothorax is a relatively frequent complication. Chemotherapy is known to induce cavitation in metastatic pulmonary nodules.
