11/83. Infantile hemifacial spasm.A 6-week-old infant had recurrent contractions of the facial musculature on the left side, which continued throughout early childhood. Surgical exploration at 5 1/2 years of age revealed a ganglioneuroma of the fourth ventricle. hemifacial spasm (HFS) in infancy and childhood suggests the possibility of serious intracranial pathologic findings.- - - - - - - - - - ranking = 1keywords = ganglion (Clic here for more details about this article) |
12/83. Suprascapular nerve entrapment secondary to a lipoma.Many causes of suprascapular nerve entrapment have been described including a small spinoglenoid notch, a tight ligament, boney spurs, and ganglion cysts. In the current patient, suprascapular nerve entrapment was caused by a lipoma in the suprascapular notch. The patient presented with painful shoulder motion that could have been attributed to rotator cuff and acromioclavicular joint disease. However, magnetic resonance imaging and electromyography were consistent with suprascapular nerve entrapment. Treatment of the rotator cuff disease and excision of the lipoma led to resolution of the patient's symptoms. This case is presented as an unusual cause of suprascapular nerve entrapment with a review of its course and anatomy.- - - - - - - - - - ranking = 1keywords = ganglion (Clic here for more details about this article) |
13/83. Pelvic presentation of a hip joint ganglion: a case report.ganglia may be found near any joint. The hip joint is one location where these lesions have been reported. In most instances the ganglia found around the hip are small, deep-seated, and not palpable. Palpable ganglia are commonly larger and present as a groin mass. We report a ganglion cyst that was not palpable due to its intrapelvic location.- - - - - - - - - - ranking = 5keywords = ganglion (Clic here for more details about this article) |
14/83. Symptomatic spinal epidural varices presenting with nerve impingement: report of two cases and review of the literature.STUDY DESIGN: Two cases of symptomatic epidural varices are presented and the literature was reviewed on this entity. OBJECTIVE: To raise awareness of this rare condition in the interpretation of preoperative magnetic resonance imaging scans and to assess the results of surgical treatment. BACKGROUND: Symptomatic epidural varices presenting with radiculopathy are extremely rare, and the diagnosis is often missed in the preoperative evaluation. This condition commonly masquerades as a herniated nucleus pulposus. diagnosis is often only made intraoperatively. MATERIALS AND methods: Case 1 is a 40-year-old man presenting with acute exacerbation of lower back pain associated with radiculopathy down his right lower limb. magnetic resonance imaging showed a paracentral disc prolapse. At operation, a congested epidural vein impinging on the L5 nerve root was noted with no intervertebral foramens stenosis. Excision of the vein was performed. The second case, a 50-year-old man with previous spinal instrumentation, was admitted for acute onset of radiculopathy down his left lower limb. At operation, an epidural varix compressing on the L4 nerve root was noted. Retrospectively, features of epidural varices were noted in the preoperative magnetic resonance imaging scans. Both patients reported resolution of symptoms after surgery. RESULTS: Excision was done for the first patient, and coagulative ablation was done in the second patient. Both patients had symptomatic relief and neurologic recovery on follow-up. CONCLUSION: Our experience and the literature demonstrated that a favorable outcome with resolution of neurologic symptoms can often be achieved after excision or ablation of the epidural varices.- - - - - - - - - - ranking = 0.00083225777583784keywords = nucleus (Clic here for more details about this article) |
15/83. Compression neuropathy of common peroneal nerve caused by an extraneural ganglion: a report of two cases.peroneal nerve entrapment is most common in the popliteal fossa, but is rarely caused by a ganglion. Although ganglionic cysts are very common lesions, they seldom cause serious complications. Ganglionic cysts developing in the sheath of a peripheral nerve or joint capsule may cause compression neuropathy. We report on two cases of compression neuropathy of the common peroneal nerve caused by an extraneural ganglion and its evaluation with magnetic resonance imaging (MRI) and ultrasonography. The differential diagnosis should involve L5 root pathology, a posttraumatic intraneural hemorrhage, a nerve compression near the tendinous arch located at the fibular insertion of the peroneal longus muscle, and a nerve-sheath tumor. The combination of MRI and ultrasonography is useful for the accurate diagnosis of this condition, and it should be treated by microsurgical exploration as soon as possible.- - - - - - - - - - ranking = 7keywords = ganglion (Clic here for more details about this article) |
16/83. Radial tunnel syndrome caused by ganglion cyst: treatment by arthroscopic cyst decompression.Compressive neuropathies of the radial nerve at the elbow can lead to one of 2 clinical entities. Posterior interosseous syndrome is primarily a motor deficiency of the posterior interosseous nerve, and radial tunnel syndrome presents as pain along the radial tunnel and extensor muscle mass. The radial nerve can be compressed at a number of sites around the elbow. In addition, numerous mass lesions reported in the literature can cause compressive neuropathy of the radial nerve at the elbow. Standard surgical management for persistent radial tunnel syndrome that is refractory to nonsurgical treatment is open decompression of the radial nerve. Cysts occurring in other joints are commonly treated arthroscopically. Supraglenoid cysts of the shoulder, meniscal cysts in the knee, and dorsal wrist ganglia are routinely treated with arthroscopic decompression or excision with management of the underlying etiology of the cyst. We present a case of radial tunnel syndrome caused by a ganglion cyst of the proximal radioulnar joint that was treated using arthroscopic excision of the cyst and decompression of the radial nerve.- - - - - - - - - - ranking = 5keywords = ganglion (Clic here for more details about this article) |
17/83. Deep peroneal nerve paresis in a runner caused by ganglion at capitulum peronei. Case report and review of the literature.Although lateral popliteal sciatic nerve damage is not one of the commonest diseases in the general population, it is quite frequent among athletes. Several physiopathologic mechanisms have been thought to bring about this damage in athletes. Soft tissue ganglions with neurological involvement of the lateral popliteal sciatic nerve or its terminal rami are in differential diagnosis with several lesions of this area, as direct or indirect trauma, subcutaneous rupture of anterior tibialis muscle and long peroneal muscle, disc hernia, intraspinal tumor, anterior tarsal tunnel syndrome, cysts, neurofibroma, baker's cyst, vascular claudication, stenosing or inflammatory pathology of 2(nd) motoneuron, antimicrobial agents for urinary tract infection (nitrofurnantoin). The authors report the case of a 34-year-old amateur athlete with a recent paralysis of the hallux extensor, paresis of the toe extensor and hyposthenia of the tibialis anterior. The patient had been suffering from episodes of lumbalgia for a long time. He was sent to us because neurological damage due to disc herniation was suspected. electromyography, sonography, and CT showed peripheral compression of the deep peroneal nerve caused by a mucous cyst at the capitulum peronei, a ''rare'' condition. The patient underwent surgery to excise the cyst, which led to the rapid resolution of the nerve deficit shown by clinical and electromyographical tests. A meticulous anamnesis and accurate objective examination, followed by specific tests (radiographs, sonography, and possibly CT scan) generally enable a correct diagnosis to be made. If diagnosis and therapy are carried out correctly, and without delay, symptoms quickly resolve and the nerve deficit progressively regresses.- - - - - - - - - - ranking = 5keywords = ganglion (Clic here for more details about this article) |
18/83. Vascular cross-compression of the VIIth and VIIIth cranial nerves.A 53-year-old male patient had been suffering from severe aural symptoms (pulsatile right-sided tinnitus and paroxysmal dizziness attacks with nausea) and right hemifacial spasm. Treatment had involved stellate ganglion block with lignocaine and the injection of intravenous sodium bicarbonate solution for attacks of Meniere's syndrome and facial nerve block with lidocaine for hemi-facial spasm. Despite these treatments, the dizzy attacks became more frequent, developing into the clustering state. air CT cisternography and vertebral angiography demonstrated an enlarged and curved vertebral artery. Vascular cross-compression of the VIIth and VIIIth cranial nerves was therefore suspected. Microvascular decompression was performed. After operation, the pulsatile tinnitus, dizziness and hemifacial spasm disappeared. From the present case and a review of the literature, we conclude that vascular cross-compression of the VIIIth cranial nerve should be an indication for microvascular decompression only when symptoms of vascular cross-compression of the VIIth cranial nerve are also seen.- - - - - - - - - - ranking = 1keywords = ganglion (Clic here for more details about this article) |
19/83. MRI diagnosis of occult ganglion compression of the posterior interosseous nerve and associated supinator muscle pathology.Occult interosseous ganglions in the proximal forearm can result in pain and decreased supination. We will describe the magnetic resonance imaging (MRI) diagnosis of an interesting case of supinator atrophy secondary to compression of the posterior interosseous branch of the radial nerve. A brief review of this entity follows.- - - - - - - - - - ranking = 5keywords = ganglion (Clic here for more details about this article) |
20/83. Intraneural ganglion of the suprascapular nerve: case report.We present a case of multicystic ganglion of the suprascapular nerve in an 18-year-old man. Pain and shoulder weakness were present and examination showed weakness and atrophy of the supraspinatus and infraspinatus muscles. electromyography showed severe denervation of the infraspinatus and supraspinatus muscles. At surgery a multicystic lesion of the suprascapular nerve extending approximately 5.7 cm from its origin was resected and reconstructed by sural nerve grafting.
