A 54-year-old Chinese woman presented for radiofrequency ablation (RFA) of benign thyroid nodules. A few hours after the procedure, the patient developed neck swelling and tenderness. Doppler ultrasound (US) images of the neck revealed haematoma with a vascular hypoechoic mass at the RFA site, suspicious for pseudoaneurysm. These findings were confirmed on subsequent on-table fluoroscopy following direct US-guided needle puncture and injection of contrast, demonstrating opacification of the mass and extravasation. Successful occlusion of the pseudoaneurysm was performed using US-guided thrombin injection. The patient made a good recovery with follow-up US 1 month later showing no recurrence of haematoma or pseudoaneurysm.
