Unintentional puncture of thyroid cyst during insertion of dialysis catheter.

Central venous catheter (CVC) for hemodialysis are frequently implanted to the internal jugular vein. Thyroid cysts are commonly shown in ultrasound examination and their recognition should not pose a problem. Herby we present an uncommon case of the thyroid cyst unintended puncture, during an attempt of CVC insertion. No further clinical consequences were observed. For all practitioners, involved in interventional nephrology, such complication may be of the utmost importance.
