Stage IVB thyroid cancer includes carotid encasement or infiltration of the prevertebral fascia and mediastinal vessels. Stage IVB disease is considered unresectable due to grave consequences of attempting resection. We report a rare case of carotid artery engulfment being resected uneventfully without carotid resection.
