Cryoablation of an aortocaval lymph node in the setting of acquired resistance during immune checkpoint inhibition. a Clinical timeline of therapy. b Poorly differentiated squamous cell carcinoma in lung tissue, mediastinal lymph node, and ablated aortocaval lymph node (H&E, original magnification X200) before cryoablation. c Baseline 18FDG PET/CT was obtained two months prior to cryoablation. Nine months follow-up PET imaging shows no recurrence of the metastatic lymph node
