This patient with a history of smoking was referred from an outside pulmonary clinic for a CT chest showing two enlarged right paratracheal nodes.  The larger structure (Image 1) was found to have a hypoechoic appearance under endobronchial ultrasound, which is atypical of a lymph node.  Upon needle aspiration, the structure collapsed and serous fluid was collected.  The smaller lymph node (Image 2) showed the normal hyperechoic presentation and yielded normal lymphatic tissue when sampled.
