Methicillin-Sensitive Staphylococcus aureus Suppurative Thyroiditis with Thyrotoxicosis.

Intravenous drug use (IVDU) can lead to numerous complications from skin abscesses to bacteremia to endocarditis. Here, we present a rare case of acute suppurative thyroiditis as a complication of IVDU, in which a 26-year-old female with a past medical history of IVDU presented to the emergency department for evaluation of a large right sided neck mass. On exam, she had signs of sepsis and thyrotoxicosis. Fine needle aspiration confirmed suppurative thyroiditis. Blood cultures and culture from fine needle aspiration grew Staphylococcus aureus. Patient was treated with 2 weeks of intravenous antibiotics with good resolution of her symptoms.
