Acute thyroiditis

Acute thyroiditis is an acute purulent infection of the thyroid. It is caused by a bacterial or fungal infection. Bacteria or fungi spread through the blood circulation, lymphatic tract, or adjacent purulent lesions and invade the thyroid gland to cause acute purulent inflammation. Among them, the most common secondary infection is the spread of adjacent purulent lesions, which is another possible cause. Acute thyroiditis is more acute, with high fever, sweating, and general discomfort. There is a local mass in the thyroid area, tenderness is obvious, and local skin is red and fever.
