Rare renal metastasis: Oligometastatic non-small cell lung cancer diagnosed with ultrasound guided renal biopsy

Metastatic renal masses present an uncommon diagnostic dilemma. Differentiating malignant metastatic renal lesions from primary renal malignancy relies on a high index of suspicion, multidisciplinary discussion, comprehensive radiological work up and finally, accurate immunohistochemical pathology findings. Here we present a rare case of solitary non-small cell lung cancer metastases to the kidney definitively diagnosed with image guided renal biopsy. We emphasize both the salient radiological features of such masses, as well as the vital role of image guided renal biopsies in such settings. The pivotal role of the radiologist within the oncological multidisciplinary team meeting is also illustrated.
