ABSTRACT
Acute suppurative thyroiditis (ST) is caused by infection of the thyroid gland. Abscess formation in acute ST is a rare, but potentially life-threatening condition. Most patients with acute ST have predisposing conditions. Herein, we report a 24-year-old female who presented on the fifth postpartum day with severe dysphagia, fever, chills, and sore throat. Thyroid hormone levels were consistent with thyrotoxicosis. Based on the clinical, radiological and laboratory findings, ST and abscess caused by Peptostreptococcus was diagnosed. The patient was successfully treated with appropriate antibiotics and ultrasound-guided abscess drainage.
