Abstract
Intraneural ganglions of the upper extremity are rare and they usually originate within the epineurium of the peripheral nerve as nonneoplastic mucinous cysts. Initially, most authors have supported the de novo theory of formation. However, recently, a unifying articular (synovial) theory has been proposed suggesting that the intramural ganglions have connections to the adjacent joints via the articular branches of the involved nerve.
