This article discusses a case study of a 68-year-old male patient with lung squamous cell carcinoma (LUSC) who developed solitary renal metastasis. The importance of routine imaging for detecting asymptomatic renal metastasis is highlighted. The efficacy of various treatment options, including nephrectomy, stereotactic body radiation therapy, and cryoablation, is explored. The study underscores the need for a multidisciplinary team approach in managing LUSC with renal metastasis, due to the lack of clear treatment guidelines.
