A thyroid abscess caused by acute suppurative thyroiditis is an uncommon disorder affecting the thyroid gland. The eminent feature of the thyroid gland in its resistance to infection happens to be a rich blood supply and adequate lymphatic drainage. Concomitantly, the high iodine content of the thyroid gland is also bactericidal. Acute suppurative thyroiditis, which leads to primary thyroid abscess, is an unusual type of head and neck infection which in a paediatric age is quite rare. We have the opportunity to present such an appreciable case. Ultrasound imaging demonstrated a fluid collection in left lobe of the thyroid gland. No surgical treatment was carried out and the case was treated successfully by oral antibiotic therapy.
