CTICasesCystic Metastases from Laryngeal Cancer
Imaging findings
CT in a patient with a laryngectomy for squamous cell carcinoma shows multiple thin-walled pulmonary cysts developing at the sites of prior solid metastatic nodules following chemotherapy.
Key takeaways
Metastases from squamous cell carcinoma (e.g., laryngeal cancer) can undergo tumor necrosis and keratin liquefaction during chemotherapy, leading to the formation of thin-walled pulmonary cysts that represent treated metastatic disease.
