Efficacy of Ultrasonography for Diagnosis and Treatment of the Ganglion Cyst that Causes Ulnar Neuropathy

Abstract

Ganglion cyst is a benign mass which is filled with gelatinous fluid, the most common soft tissue tumor in the hand and wrist. In this article, we reported a 40-year-old male who had a ganglion cyst and presented with the ulnar neuropathy findings. Ultrasonographic (US) examination was performed on the patient who was resistant to the treatment. The ganglion cyst that compresses the ulnar nerve in the wrist was detected and aspirated by ultrasound guidance. After the aspiration, there was a significant improvement in the hand functions of the patient who was a musician and playing guitar. Diagnosis and USguided aspiration of the wrist ganglion cyst is reliable, easy and quite effective with high patient satisfaction.
