A lump on the laryngeal node may be caused by localized lymph node enlargement, thyroid nodules and thyroglossal cysts. 1. Localized lymph node enlargement: it may be due to recurrent local inflammation such as pharyngitis and tonsillitis, triggered by the reactive enlargement of lymph nodes, which externally manifests the phenomenon of a bag on the laryngeal node. 2. Thyroid nodules: they may also be caused by thyroid nodules. The thyroid gland is located in the vicinity of the thyroid cartilage in the human body, and when nodules appear on the thyroid gland, the phenomenon of a bag on the laryngeal nodes may appear. 3. Thyroglossal cysts: usually caused by congenital deformity of the patient’s neck, usually manifested as a spherical bulge under the skin of the neck, which can be moved up and down with swallowing and is often located in the midline of the neck, that is, on the laryngeal node. Therefore, it is recommended that patients go to the hospital in time for a detailed examination to clarify the cause of the disease and then carry out targeted treatment.
