Physical Examination
The most common signs of acute infectious thyroiditis are a fever and neck tenderness.
Anatomical variations, like a fistula, can be identified as well.
However, imaging might not distinguish infectious thyroiditis from subacute (noninfectious) thyroiditis.
Blood Tests
You may need blood tests.
A blood culture may also be helpful in identifying bacteria or another microorganism that’s causing your infection.
Suppurative infectious thyroiditis is usually more severe than non-suppurative thyroiditis.
The culture results can help your healthcare provider choose the appropriate antibiotic and/or anti-fungal medication for treatment.
How Is Acute Infectious Thyroiditis Treated?
The treatment of acute thyroiditis is focused on eliminating the infection and reducing symptoms while the infection resolves.
The usual treatment for acute infectious thyroiditis is a combination of incision and drainage coupled with antibiotics.
Antibiotics
Oral antibioticscan be used for the treatment of acute bacterial infectious thyroiditis.
If your healthcare provider is concerned that you could have anantibiotic-resistant infection, another antibiotic may be selected.
You may have percutaneous drainage at the same time as your FNA.
If you have this procedure, you will probably also receive antibiotic treatment.
Rarely, surgical removal of part of the thyroid gland may be needed.
