Current Case:

A 51-years old treated for buccal carcinoma presented with a new right thyroid lesion and mediastinal nodes.

The oncologist wanted a biopsy of both, the thyroid lesion and one of the mediastinal nodes.

Since it was not possible to bring the USG machine into the CT room and since it made no sense to do two separate procedures, it was decided to do both procedures at the same time, under CT scan guidance

The video discusses the case, the approach and though USG is the preferred mode to biopsy thyroid lesions, when, why and how, CT guidance is used in select situations.
