This is a 57-years old man with renal cell carcinoma. He had a growing swelling in the frontal bone region. A PET/CT showed a mass destroying the frontal sinus and another nodule in the subcutaneous region of the right upper back.

Sometimes you wonder…this biopsy could have been done blindly by the physician / surgeon, but more and more all of these come for image-guided, I guess to ensure there is no complication whatsoever.

I used an 18G coaxial biopsy gun with an oblique approach to biopsy the lesion, which turned out to be metastasis from renal cell carcinoma (RCC).
