title: Ultrasound-guided percutaneous ethanol injection in papillary thyroid cancer metastatic lymph-nodes.
abstract: Post-operative neck nodal metastases are detected in 9-20 % of papillary thyroid cancer (PTC). Ultrasound-guided ethanol injection (UPEI) has been used with promising results in the treatment of PTC patients with limited number of lymph-node metastases.
  
  
  METHODS
  We report the imaging and biochemical documentation of UPEI results in four metastatic neck lymph-nodes of papillary thyroid-cancer. A significant reduction both in the diameter of the lymph-nodes and in the serum thyroglobulin levels were observed in all cases and have been reported in a step-by-step sequence.
  
  
  CONCLUSIONS
  the UPEI treatment is a simple and suitable tool for the treatment of PTC cervical lymph-node metastases.
