Ultrasound-Guided Ganglionectomy of a Flexor Hallucis Longus Ganglion Cyst Using Coablation Technology: A Case Report.

A 44-year-old woman with a history of an open ganglionectomy 2 years prior presented with a recurrent ganglion cyst. The ganglion cyst, extending from the flexor hallucis longus tendon sheath, was confirmed with magnetic resonance imaging. The patient declined another surgical incision. An experimental procedure was performed: ultrasound-guided ganglionectomy using a coablation wand. She achieved full symptom resolution, with no recurrence 1 year afterwards. To our knowledge, this is the first case report in the literature describing the use of this instrument for treating a ganglion cyst.
