We describe the case of a 74-year-old man with stage IV esophageal adenocarcinoma and prior hepatic, retroperitoneal nodal, and cerebral metastases who developed a new hypermetabolic lesion in the left kidney on Positron Emission Tomography/Computed Tomography (PET/CT) . MRI identified a 3.4 cm enhancing mass, and biopsy confirmed poorly differentiated metastatic adenocarcinoma. The lesion was treated with CT-guided cryoablation using a dual freeze-thaw protocol. The patient tolerated the procedure well, and a small upperpole bleed identified immediately post-procedure was successfully managed with selective coil embolization. He resumed systemic therapy and remained asymptomatic at the four-week follow-up, with a complete metabolic response at the ablation site on the follow-up PET/CT. This case illustrates the feasibility of CT-guided percutaneous cryoablation as a minimally invasive option for local control of renal metastases in patients with esophageal cancer.  \nCategories: Urology, Radiology, Oncology  \nKeywords: cryoablation, ct guided ablation, esophageal adenocarcinoma, image guided therapy, interventional radiology, oligometastasis, percutaneous ablation, renal metastasis, thermal ablation, tumor ablation  \nIntroduction  \nEsophageal adenocarcinoma most commonly metastasizes to the liver, lungs, bone, and lymph nodes, while renal involvement is uncommon and primarily reported in isolated case reports or small series [1,2] . These reports suggest that renal metastasis occurs far less frequently than the involvement of typical metastatic sites, and the true incidence remains undefined [1,2] . Because such presentations are infrequent, management strategies for isolated renal metastases remain undefined [1,2] .  \nImage-guided percutaneous ablation offers a minimally invasive means of achieving local tumor control while preserving renal function and minimizing interruption of systemic therapy [3-6]. Among the available modalities, cryoablation provides precise visualization of the ablation zone and limits collateral injury [4-6]. Its ability to monitor the ice-ball margin in real time, preserve surrounding renal parenchyma, and offer nephron-sparing treatment makes it particularly relevant for managing uncommon, isolated renal lesions inpatients who may not be ideal surgical candidates [3,5] .  \nThis report describes a case of computer tomography (CT)-guided percutaneous cryoablation for a renal metastasis of esophageal adenocarcinoma, demonstrating the feasibility and safety of image-guided therapy in an uncommon metastatic setting.  \nCase Presentation  \nA 74-year-old man with stage IV esophageal adenocarcinoma and known metastases to the liver and retroperitoneal lymph nodes was under active systemic therapy. He had previously undergone stereotactic body radiation therapy to the retroperitoneal lymph nodes and craniotomy followed by postoperative radiotherapy for a left parietal brain metastasis.
