Symptoms And Signs

Introduction : Intraneural ganglion cysts (INGCs) are an infrequent cause of foot drop. INGCs are benign mucinous cysts within the epineurium of peripheral nerves, which are usually observed in the peroneal nerve at the knee typically leading to symptoms and signs of peripheral neuropathy. Case Report: A 40-year-old man with foot drop who had undergone a spinal study for discopathy was examined in this study. The patient had peroneal nerve compression at the neck of the fibula resulting from an extra neural cyst. Surgical exploration revealed an intraneural cyst. Epineurium was incised and the cyst was evacuated. In a two-week post-surgery follow up, his foot drop had improved partially and the remainder of his symptoms resolved. Conclusion: Awareness of the intraneural cysts of peroneal nerve as a cause for foot drop is important because early surgical intervention could reverse the course of disease.

Post Operation

Intraneural ganglion cysts are a relatively uncommon cause of peroneal nerve palsy. Patient’s typically present with weakness or absent ankle dorsiflexion, knee or leg pain, and paresethesia. Surgical decompression is widely accepted as the first line treatment for intraneural ganglion cysts of the peroneal nerve, with earlier intervention associated with better functional outcomes. Here, we describe the case of a 57-year-old male found to have a intraneural ganglion cyst of the peroneal nerve, three months after the onset of symptoms, including eventual complete foot drop. He underwent surgical decompression of the cyst. The intraneural ganglion cyst was found to be intricately involved with the nerve fibers, and the patient still does not have the ability to dorsiflex the affected ankle one month post-operation.

Nerve Recovery

Background: Intraneural ganglion cysts (IGC) are non-neoplastic mucinous cysts that form when thick mucinous fluid accumulates in the epineurium of peripheral nerves, with the majority of cases occurring in the para-articular or articular areas. Case Presentation: The two cases of a 69-year-old man and a 59-year-old man who acquired peroneal nerve neuropathy as a result of an intraneural ganglion cyst are presented here. The L.L.R.M. Medical College Department of Orthopedics provided care for them. There was complete nerve recovery in all patients after substantial cyst wall dissection and secretion removal. Conclusion: An intraneural ganglion cyst and trauma may exacerbate nerve damage, despite the fact that it is difficult to detect the cyst before surgery. An early diagnosis and prophylactic actions are typically associated with better outcomes. KEY WORDS: Intraneural ganglion, Common peroneal nerve, Foot drop.

Intraneural ganglion cysts are nonneoplastic, mucinous cysts within the epineurium of peripheral nerves which usually involve the peroneal nerve at the knee. A 37-year-old female presented with progressive left buttock and posterior thigh pain. Magnetic resonance imaging revealed a sciatic nerve mass at the sacral notch which was subsequently revealed to be an intraneural ganglion cyst. An intraneural ganglion cyst confined to the proximal sciatic nerve has only been reported once prior to 2009.

The Common

Lower extremities peripheral neuropathies caused by ganglion cysts are rare. The most frequent location of occurrence is the common peroneal nerve and its branches, at the level of the fibular neck. We report the case of a 57-year-old patient admitted with foot drop, due to an extraneural ganglion of the upper tibiofibular syndesmosis, compressing the deep branch of the peroneal nerve. Although there have been many previous reports of intraneural ganglion involvement with the lower limb nerves, to our knowledge, this is the second reported occurrence of an extraneural ganglion distinctly localized to the upper tibiofibular syndesmosis and palsying deep peroneal nerve. The diagnosis was made preoperatively using MRI. The common peroneal nerve and its branches were recognized and traced to its bifurcation during the operation, and the ganglion cyst was removed. Two months after surgery, the patient was pain-free and asymptomatic except for cutaneous anesthesia in the distribution of the deep peroneal nerve.

OBJECTIVEIntraneural ganglion cysts are rare and benign mucinous lesions that affect peripheral nerves, most frequently the common peroneal nerve (CPN). The precise pathophysiological mechanisms of intraneural ganglion cyst development remain unclear. A well-established theory suggests the spread of mucinous fluid along the articular branch of the peroneal nerve as the underlying mechanism. Clinical outcome following decompression of intraneural ganglion cysts has been demonstrated to be excellent. The aim of this study was to evaluate the correlation between clinical outcome and ultrasound-detected morphological nerve features following decompression of intraneural ganglion cysts of the CPN.METHODSData were retrospectively analyzed from 20 patients who underwent common peroneal nerve ganglion cyst decompression surgery at the Universität Ulm/Günzburg Neurosurgery Department between October 2003 and October 2017. Postoperative clinical outcome was evaluated by assessment of the muscular strength of the anterior tibial muscle, the extensor hallucis longus muscle, and the peroneus muscle according to the Medical Research Council grading system. Hypesthesia was measured by sensation testing. In all patients, postoperative morphological assessment of the peroneal nerve was conducted between October 2016 and October 2017 using the iU22 Philips Medical ultrasound system at the last routine follow-up appointment. Finally, the correlations between morphological changes in nerve ultrasound and postoperative clinical outcomes were evaluated.RESULTSDuring the postoperative ultrasound scan an intraneural hypoechogenic ring structure located at the medial side of the peroneal nerve was detected in 15 (75%) of 20 patients, 14 of whom demonstrated an improvement in motor function. A regular intraneural fasicular structure was identified in 3 patients (15%), who also reported recovery. In 1 patient, a recurrent cyst was detected, and 1 patient showed intraneural fibrosis for which recovery did not occur in the year following the procedure. Two patients (10%) developed neuropathic pain that could not be explained by nerve ultrasound findings.CONCLUSIONSThe results of this study demonstrate significant recovery from preoperative weakness after decompression of intraneural ganglion cysts of the CPN. A favorable clinical outcome was highly correlated with an intraneural hypoechogenic ring-shaped structure on the medial side of the CPN identified during a follow-up postoperative ultrasound scan. These study results indicate the potential benefit of ultrasound scanning as a prognostic tool following decompression procedures for intraneural ganglion cysts of the CPN.

AbstractIntraneural ganglion cysts are rare mucinous cyst originating within the epineurium of peripheral nerves. They occur most commonly in the peroneal nerve. However, they have also been described in many nerves in the vicinity of synovial joints. Intraneural ganglion cysts in the upper extremity are rare. Those at the elbow joint comprise only 9% of intraneural ganglion ever reported.A 66-year-old and right-handed male patient presented with a sudden onset of right-hand weakness. He initially noticed paresthesia with decreased sensation in the lateral two digits and radial palm in his right hand. Physical examination showed thenar muscle atrophy and muscle weakness of the abductor pollicis brevis in the right hand. Preoperative diagnosis of intraneural ganglion cyst was made on the basis of characteristic magnetic resonance imaging (MRI) findings. On exploration, the ulnar nerve was identified proximal to the elbow joint. Its articular branch was addressed and divided from the elbow joint.To the best of our knowledge, addressing the articular branch connecting the glenohumeral joint for the treatment of intraneural ganglion at the elbow has only been reported twice. We experienced a rare occurrence of intraneural ganglion cyst at the elbow manifesting an ulnar neuropathy. Here, we report intraoperative findings for the articular branch-connected to intraneural ganglion of the ulnar nerve at the elbow. Early diagnosis of intraneural ganglion with precise identification of the pathology and addressing the articular branch with atraumatic dissection of ganglion cyst are essential to achieve successful treatment for this rare lesion.
