Muscular hypertrophy is caused mainly due to myopathic disorder. But, it is also rarely produced by neurogenic disorder. A 74-year-old woman complained of right calf pain with hypertrophy for several years. Recent lumbar spine magnetic resonance imaging (MRI) showed central and lateral canal narrowing at the L4-L5 intervertebral space. Lower extremity MRI revealed fatty change of right medial head of the gastrocnemius and soleus, causing right calf hypertrophy. Electrodiagnostic examinations including electromyography and nerve conduction velocity testing demonstrated $5^{th}$ lumbar and $1^{st}$ sacral polyradiculopathy. Integrating all the results, the diagnosis was neurogenic muscle hypertrophy. Neurogenic muscle hypertrophy is very rare, but we recommend that clinicians consider this problem when a patient complains of lower limb hypertrophy and pain.

This report describes a rare case of postoperative hyperventilation attack after an endoscopic third ventriculostomy in a 46-year-old woman. About 60 min after the termination of the operation, an intractable hyperventilation started with respiratory rate of 65 breaths/min and $EtCO_2$, 16.3 mm Hg. Sedation with benzodiazepine, thiopental sodium, fentanyl, and propofol/remifentanil infusion was tried under a rebreathing mask at a 4 L/min of oxygen. With aggressive sedative challenges, ventilation pattern was gradually returned to normal during the 22 hrs of time after the surgery. A central neurogenic hyperventilation was suspected due to the stimulating central respiratory center by cold acidic irrigation solution during the neuroendoscopic procedure.

Neurogenic muscular atrophy is muscle wasting and weakness caused by trauma or disease of the nerve that innervates the muscle. We describe a case of unilateral trigeminal neuropathy and neurogenic muscular atrophy of the masticatory muscle caused by a tumor in the foramen ovale. A 59-year-old man visited our clinic complaining of difficulty in right-sided mastication. There were no evident clinical signs and symptoms of temporomandibular disorder. However, severe atrophy of the right masseter and temporalis muscles and hypesthesia of the right side mandibular nerve area were confirmed. Through T1 and T2 signals on magnetic resonance imaging (MRI), a mass suspected of a neurogenic tumor was observed in the foramen ovale and cavernous sinus. Severe atrophy of all masticatory muscles on the right side was observed. This rare case shows trigeminal neuropathy caused by a tumor around the foramen ovale and atrophy of the ipsilateral masticatory muscles. For an accurate diagnosis, it is essential to identify the underlying cause of muscle atrophy with neurologic symptoms present. This can be done through a more detailed clinical examination, including sensory testing and brain MRI, and consider a referral to neurology or neurosurgery for the differential diagnosis of the intracranial disorder.

Neurogenic tumors of the mediastinum may have an intraspinal component connected by a narrowed segment of tumor in the intervertebral foramen, then have symptoms of back pain,lower extremity tingling sensation. CT scan or MRI demonstrated a Dumbbell-shaped mass density compressing spinal canal, enlargement of the foramen, erosion of bone, and intervertebral widening. We report the analysis of the 18 cases of neurogenic tumors on posterior mediastinum and Dumbbell type tumors are 3 cases among the 18 cases. The neurilemmomas were 12 cases[67%], the ganglioneuroma were 5 cases[28%], and neuroblastoma was one case[5%]. The successful removal was done in all cases, a standard thoracotomy and laminectomy was done in Dumbbell type tumors.There was no postoperative neurological complications.

Epiduroscopy is defined as a percutaneous, minimally invasive endoscopic investigation of the epidural space. Periduroscopy is currently used mainly as a diagnostic tool to directly visualize epidural adhesions in patients with failed back surgery syndrome (FBSS), and as a therapeutic action in patients with low back pain by accurately administering drugs, releasing inflammation, washing the epidural space, and mechanically releasing the scars displayed. Considering epiduroscopy a minimally invasive technique should not lead to underestimating its potential complications. The purpose of this review is to summarize and explain the mechanisms of the side effects strictly related to the technique itself, leaving aside complications considered typical for any kind of extradural procedure (e.g. adverse reactions due to the administration of drugs or bleeding) and not fitting the usual concept of epiduroscopy for which the data on its real usefulness are still lacking. The most frequent complications and side effects of epiduroscopy can be summarized as non-persistent post-procedural low back and/or leg discomfort/pain, transient neurological symptoms (headache, hearing impairment, paresthesia), dural puncture with or without post dural puncture headache (PDPH), post-procedural visual impairment with retinal hemorrhage, encephalopathy resulting in rhabdomyolysis due to a dural tear, intradural cyst, as well as neurogenic bladder and seizures. We also report for first time, to our knowledge, a case of symptomatic pneumocephalus after epiduroscopy, and try to explain the reason for this event and the precautions to avoid this complication.

Back pain has plagued humans for many thousands of years. The treatment of back pain is divided into operative treatment and conservative treatment. It is reported that cure rate of conservative treatment is 80~90 percent. Generally, the treatment of oriental medicine is mostly conservative treatment. But, surgery should not be used as a last resort in treatment; it is just one of many treatment options for various spinal conditions. In some instance, it can be to preferred choice; in other situations, alternative therapies may be superior. Selections of the operation in HIVD 1. Acute disc herniations with a protracted significant component af back pain. 2. Chronic disc degeneration with significant back pain and degeneration limited to one or two disc levels. 3. Sugical instability created during decompression. 4. The presence of neural arch defects coincident with disc disease. 5. Symptamatic and radiographically demonstrable segmental instability. Selections of the operation in stenosis 1. If it does not slowly progress in physical therapy and other nonoperative measures, many of these patients may ultimately need surgical decompression. 2. Absolute stenosis in an impression of CT, MRI.(under 10mm) 3. In patients with established symptoms of .neurogenic claudication. 4. In patients with bad influence of neurogenic derangement.(strength, sensory) Selections of the operation in spondylolisthesis 1. Persistence or recurrence of major symptoms for at least one year despite activity modification and physical therapy. 2. Tight hamstrings, persistently abnormal gait, or postural deformities unrelieved by physical therapy. 3. Sciatic scoliosis. 4. Progressive neurologic deficit. 5. Progressive slipping beyond 25 or 50 percent, even when asymptomatic. 6. A high slip angle (40 to 50 degrees) in a growing child, since it is likely to be associated with further progression and deformity. 7. Psychologic problems attributed to shortness of trunk, abnormal gait, and postural deformities characteristic of more severe slips.

Interstitial cystitis is an extremely painful and distressing condition, characterized by severe suprapubic pain, which increases with bladder filling and is relieved by voiding. The daily frequency of micturition may approach 100 times, but no incontinence is observed. The symptoms persist throughout the night, which consequently affects sleep. The etiology of this condition is still unknown, but includes infection, autoimmune response, allergic reaction, neurogenic inflammation, epithelial dysfunction and inherited susceptibility. Herein, a case of interstitial cystitis, with severe symptoms, which was successfully treated with lumbar sympathetic block, is reported.

Neurogenic tumors are common in posterior mediastinal tumors. In most cases, tumors were accidentally showed on simple chest X-ray. In some cases, they were presented by symptoms which were induced by nerve compression or airway compression. But as in our case, neurogenic tumor with spontaneous hemothorax is very rare. A 45-year-old man admitted to emergency room of other hospital because of acute right chest pain and dyspnea. A chest X-ray showed a right pleural effusion. Hemothorax was diagnosed after closed thoracostomy. Following chest CT showed posterior mediastinal mass. The patient was transferred to our hospital. T spine MRI showed dumbbell shaped mass. Diagostic impression was neurogenic tumor. The pathologic result was neurilemmoma after surgical resection.

Objective : Traumatic lumbar burst fracture causes significant spinal cord injury. This report is intended to estimate the efficacy using oriental treatment on a patient with lumbar burst fracture and spinal cord injury. Methods : From 21th December, 2009 to 5th February, 2010, 1 female inpatient diagnosed with lumbar burst fracture and spinal cord injury was treated with general oriental medicine therapy : mae-sun therapy ; acupuncture ; moxibustion ; pharmacopuncture ; physical therapy and herbal medication. TUG, SCIMII and VAS were used for evaluation of gait disturbance and pain in both feet. Measurement of self voiding amount and remaining amount through CIC was used for evaluation of neurogenic vesical dysfunction. Results : The patient showed a certain degree of improvement in gait disturbance, pain in both feet and neurogenic vesical dysfunction through above evaluation methods. Conclusion : Oriental treatments such as mae-sun therapy, acupuncture and moxibustion therapy, pharmacopuncture therapy and herbal medication can be effective for spinal cord injury due to traumatic lumbar burst fracture.

Objective : The central opioid mechanism of acupuncture analgesia has been fairly well documented in acute behavioral experiments, but little electrophysiological study has been performed on the peripheral mechanism and subtypes of opioid receptors responsible for acupuncture-induced antinociception in chronic animal models. In the present electrophysiological experiment, we studied the peripheral mechanism and opioid receptor subtypes which Were implicated in electroacupuncture-induced antinociception in the rat with chronic inflammatory and neurogenic pain. Methods : In the rat with complete Freund's adjuvant-induced inflammation and spinal nerve injury, dorsal horn cell responses to afferent C fiber stimulation were recorded before and after electroacupuncture (EA) stimulation applied to the contralateral Zusanli point for 30 minutes. Also studied Were the effects of specific opioid receptor antagonists and naloxone methiodide, which can not cross the blood-brain barrier, on EA-induced inhibitory action. Results : EA-induced inhibitory action was significantly attenuated by naloxone methiodide, suggesting that EA-induced inhibition was mediated through peripheral mechanism. Pretreatment, but not posttreatment of naltrexone and spinal application significantly blocked EA-induced inhibitory actions. In inflammatory and neurogenic pain models, ${\mu}-$ and ${\delta}-opioid$ receptor antagonists (${\beta}-funaltrexamine$ & naltrindole) significantly reduced EA-induced inhibitory action, but ${\kappa}-opioid$ receptor antagonist had weak inhibitory effect on EA-induced antinociception. Conclusion : These results suggest that 2Hz EA-stimulation induced antinoeiceptive action is mediated through peripheral as well as central mechanism, and mainly through ${\mu}-$ and ${\delta}-opioid$ receptors.
