A Ganglion Within the Ulnar Nerve and Communication With the Distal Radioulnar Joint via an Articular Branch: Case Report

Intraneural Ganglions of the Hand and Wrist

“…1e6, 30 Understanding the pathomechanics of development of intraneural ganglion means that complete excision of the ganglion may not be necessary and may even be harmful. 7,8,15,19,22,23,34 In all of our 8 patients who were operated upon after introduction of the articular theory, an articular branch was identified. However, the articular branch was identified in 4 of them after dissection of the ganglion off the nerve fascicles.…”

“…Now, with the understanding of the pathological features of intraneural ganglions and how they are connected to the joint via the articular branch, most surgeons have adopted a simpler technique of searching for and excising the articular branch and decompressing the ganglion by either aspiration or unroofing. 7,8,15,19,22,23 Patients may present with a painless mass or with symptoms and signs of nerve irritation or compression depending on the size and location of the ganglion. Usually there is no pain in the involved joint.…”

Intraneural ganglion cyst of the ulnar nerve in an unusual location: A case report

“…Most intraneural ganglions documented in the literature involved the common peroneal nerve in the fibular neck region. Involvement of the peripheral nerves of the upper extremities with an intraneural ganglion is an extremely rare presentation [5]. The most commonly involved peripheral nerve in this rare presentation is the ulnar nerve; the most common location is the elbow in an upper extremity [6].…”

Intraneural Ganglion in Superficial Radial Nerve Mimics de Quervain Tenosynovitis

“…These lesions are generally associated with neurologic symptoms including numbness, paresthesias, radiating pain, or motor weakness. [1][2][3][4] The pathogenesis of these lesions remains unclear. In an effort to guide treatment, there are several proposed theories for the development of intraneural ganglions.…”
