“…Subsequently, we confirmed our theory at all other sites: including the upper and lower limbs (from the shoulder to finger, and the hip to the toe). The ulnar nerve represents the second most common site for intraneural ganglion cysts (Hung et al, 2018;Krishnan et al, 2017;Spinner et al, 2006a;Spinner et al, 2009;Spinner et al, 2018;Wang et al, 2009). We challenged and confirmed the theory by testing apparent clinical outliers in the literature (Laumonerie et al, 2016;Spinner et al, 2008a;Spinner, Wang, et al, 2012;Spinner et al, 2019).…”

By recognizing anatomic and radiologic patterns of rare and often misdiagnosed peripheral nerve tumors/lesions, we have defined mechanisms for the propagation of neural diseases. The novel concept of the nervous system serving as a complex system of "highways" driving the neural and perineural spread of these lesions is described in three examples: Intraneural dissection of joint fluid in intraneural ganglion cysts, perineural spread of cancer cells, and dissemination of unknown concentrations of neurotrophic/inhibitory factors for growth in hamartomas/choristomas of nerve. Further mapping of these pathways to identify the natural history of diseases, the spectrum of disease evolution, the role of genetic mutations, and how these neural pathways interface with the lymphatic, vascular, and cerebrospinal systems may lead to advances in targeted treatments.

“…According to the synovial (articular) theory, many authors recommend dissection of the articular branch of the nerve because they believe that it is the origin of the cyst. 1,16–18 In our case, we released and decompressed the ulnar nerve completely and ensured that there were no branches connected with the joint. Dissection and excision of the cyst from the nerve is difficult and requires magnification, even though it has the potential to injure the nerve fascicles.…”

An intraneural ganglion cyst of the ulnar nerve at the wrist: a case report and literature review

Background Intraneural ganglion cysts of the ulnar nerve at the wrist are rare and poorly understood. We report a case of an intraneural ganglion cyst at the level of the wrist. Case presentation: A 48-year-old man presented with the complaints of weakness for 6 months and serious aggravation for 1 month in his right hand. After examinations, including ultrasound, the patient was diagnosed with an intraneural ganglion cyst. Intraoperatively, with exposure of the ulnar nerve, we found that the intraneural ganglion cyst was at the level of Guyon’s canal and extended approximately 6 cm proximally. Postoperatively, sensation of the fingers was normal, but atrophy of his muscles and limited straightening of his ring and little fingers were similar to those preoperatively. Conclusions Diagnosis of an intraneural cyst before surgery is mostly based on ultrasound and magnetic resonance imaging. Transection of the articular branch is an important measure to prevent recurrence of this cyst. If the ulnar nerve is compressed and causes symptoms, nerve decompression, including removal/aspiration of the cyst, and sometimes external neurolysis of the nerve, are necessary to relieve the symptoms and allow regeneration of the nerve. However, these should be performed without damaging the nerve fascicles.

Background: Intraneural ganglion cysts are nonneoplastic mucinous cysts that form by the accumulation of thick mucinous fluid in the epineurium of peripheral nerves. Symptoms arise from mechanical compression of adjacent nerve fascicles from the intraneural ganglion cyst, and include local or radiating pain, paresthesias, weakness, and muscle atrophy. Methods: Retrospective review of three cases of symptomatic intraneural ganglion cysts affecting the upper and lower extremity. Results: In our cases, the intraneural ganglion cysts were completely decompressed with resection of the articular branches, leading to improvement in the patient’s symptoms. Conclusions: Treatment of intraneural ganglion cysts requires an understanding of the underlying anatomy and pathophysiology; accurate early diagnosis is important and can lead to timely treatment and better outcomes.
