This is a 55-years old lady treated for carcinoma breast. A post-chemo PET/CT showed a new left internal mammary node as compared to an earlier normal PET/CT. The node was non-necrotic.
In such instances, a biopsy is mandatory to differentiate metastasis from infection. There wasn’t a clear para-sternal route, so instead of mucking around, we sedated her and went through the overlying costal cartilage, with an 18G coaxial biopsy gun.
The diagnosis was metastasis from carcinoma breast.
