case_images: Intraoperatively, the left neck mass was seen to be similar in appearance to the thyroid gland, with a more richly vascularized surface, but with no connection to the thyroid gland, and after separation and resection, a nodular mass of about 3.5*2.5 cm in size, with a light brown texture on the cut surface and a partially periosteal membrane was seen in the bulk, see  Figures 1C, D .
