Ultrasound-guided aspiration and injection of an intraneural ganglion cyst of the common peroneal nerve.

ABSTRACT:

Background

Intraneural ganglion cysts are rare, benign, mucinous lesions that occur within neural sheaths and are thought to involve cystic fluid exiting from nearby synovial joints. They often present as tender masses causing paresthesias in the distribution of the involved nerve, muscle weakness or cramping, or localized or referred pain.

Case description

Literature review

Standard of care has previously involved surgical resection, but this has been associated with a high frequency of recurren
