Older adult dog with vague history of weight loss.

The vet requesting the u/s thought he saw a possible mass around the cranial trachea on rads.  I wasn’t convinced but figured I’d check the neck, cranial mediastinum and abdomen.

There is a small nodule to the left lateral side of the mid-trachea. Can you help identify what it is?  I haven’t done a lot of neck ultrasounds.  I’ve got stills and videos of it in transverse and sagittal views.  It was not particularly vascular.

Thanks!
