Current Case:

A 68-yrs old treated for colon cancer with liver metastasis 2 years ago and for a thyroid oncocytic carcinoma a few months ago presented with multiple lung nodules on a PET/CT.

The medical oncologist wanted a biopsy to confirm the exact histology.

I decided to do the biopsy in the prone position from a nodule in the upper or mid-zone so as to get better breath control.

This nodule in the superior segment of the left lower lobe was the best bet, measured an average size of 3.1 mm and a z-axis of 3.0 mm.

The video discusses the case, the biopsy approach, how the small lung nodule was pierced and a discussion of other similar small <5 and <4 mm lung nodule biopsies.

When and Why Would You Prefer a Branded Drug Over a Generic!
Given the issues with quality assurance in our country, it may be better for those who can afford to buy branded drugs rather than generics.
