Yes: There is always a little bit of tissue left behind after thyroid is removed due to surrounding structures and surgeon not wanting to damage them. Usually patients who need it are given radioactive iodine after surgery to kill any residual tissue. D/w your doctor results further but does not sound worrisome.

No tissue: After thyroidectomy one hopes to see very little if any residual thyroid tissue. Treatment with radioactive iodine will typically eliminate any residual thyroid tissue. Your ultrasound sounds good. A hypoechoic nodule measuring 6 mm may be a lymph node. We typically follow this with a repeat ultrasound in 6-12 months.

Not with ablation: Sometimes microscopic tissue remains and usually is detected by scanning with i123 or i131, radio tracers, that are taken up by thyroid tissue. Usually with cancer no tissue is desired and is usually destroyed by combination of surgery and radio iodine therapy.
