Dear Editor,
Over two-third of patients initiated on hemodialysis (HD) in India have temporary catheters as the initial venous access.[1] Bloodstream infections caused by infection of the catheters can lead to metastatic complications like infective endocarditis and septic arthritis.[2] We report a case of acute suppurative thyroiditis in an end-stage kidney disease (ESKD) patient with a history of prolonged use of non-tunneled catheter.
A 35-year-old male had been undergoing HD through a right internal jugular non-tunneled catheter for three months. He presented to us with complaints of high fever, chills and rigors, swelling of the neck, and dysphagia for 10 days. Local examination revealed a large, tender, warm, and fluctuant anterior neck mass [Figure 1a].

Contrast-enhanced computed tomography of the neck revealed multiple loculated hypodense collections, approximating around 90 cc and showing enhancement of walls and septa in both lobes of the thyroid: these were suggestive of acute suppurative thyroiditis [Figure 1b]. Blood cultures sent from the catheter, peripheral blood, and pus culture from the thyroid abscess grew methicillin-resistant Staphylococcus aureus (MRSA). Henceforth, a diagnosis of metastatic thyroid abscess secondary to catheter-related bloodstream infection was considered.
The catheter was removed followed by ultrasound-guided drainage of the abscess and antibiotics as per culture sensitivity. There was complete resolution of the abscess [Figure 1c].
Metastatic infections have been observed in approximately 5%–10% of patients undergoing HD through central venous catheters.[3] The tough capsule, high iodine content, and good lymphatic drainage make the thyroid gland resistant to infections.[4] We could find only one other case[5] that reported acute suppurative thyroiditis in an ESKD patient. CRBSI presenting as thyroid abscess is extremely rare and should always be suspected in any HD patient with painful neck swelling.
