Spinal intradural extramedullary metastasis are very rare. The authors report a case of spinal metastasis at the T5 level in the intradural extramedullary space in a 76-year-old man who presented with paraparesis and sciatica. Preoper-ative neuroradiologic imaging studies were highly suggestive of intradural mass lesion with compressive myelopathy. Pathology revealed metastatic squamous cell carcinoma. We describle the mechanism of tumor spread in intradural spinal metastasis.

Brown tumors also called as osteoclastomas, are rare nonneoplastic lesions that arise in the setting of primary or secondary hyperparathyroidism. Parathyroid adenomas or hyperplasia constitute the major Brown tumor source in primary hyperparathyroidism while chronic renal failure is the leading cause in secondary hyperparathyroidism. Most of the patients with the diagnosis of primary hyperparathyroidism present with kidney stones or isolated hypercalcemia. However, nearly one third of patients are asymptomatic and hypercalcemia is found incidentally. Skeletal involvement such as generalized osteopenia, bone resorption, bone cysts and Brown tumors are seen on the late phase of hyperparathyroidism. The symptoms include axial pain, radiculopathy, myelopathy and myeloradiculopathy according to their locations. Plasmocytoma, lymphoma, giant cell tumors and metastates should be ruled out in the differential diagnosis of Brown tumors. Treatment of Brown tumors involve both the management of hyperparathyroidism and neural decompression. The authors report a very rare spinal Brown tumor case, arisen as the initial manifestation of primary hyperparathyroidism that leads to acute paraparesis.

Intracisternal accessory nerve schwannomas are very rare; only 18 cases have been reported in the literature. In the majority of cases, the tumor origin was the spinal root of the accessory nerve and the tumors usually presented with symptoms and signs of intracranial hypertension, cerebellar ataxia, and myelopathy. Here, we report a unique case of an intracisternal schwannoma arising from the cranial root of the accessory nerve in a 58-year-old woman. The patient presented with the atypical symptom of hoarseness associated with recurrent laryngeal neuropathy which is noted by needle electromyography, and mild hypesthesia on the left side of her body. The tumor was completely removed with sacrifice of the originating nerve rootlet, but no additional neurological deficits. In this report, we describe the anatomical basis for the patient's unusual clinical symptoms and discuss the feasibility and safety of sacrificing the cranial rootlet of the accessory nerve in an effort to achieve total tumor resection. To our knowledge, this is the first case of schwannoma originating from the cranial root of the accessory nerve that has been associated with the symptoms of recurrent laryngeal neuropathy.

Cervical disc herniations can press on the spinal cord and cause a problem called cervical myelopathy. The most common symptom of cervical disc herniation is neck pain that spreads down to the upper limb in various locations. There can also be associated with weakness and movement disorders of upper limb. In Oriental medicine, cervical disc herniation is treated with herb-med, physical therapy, acupuncture, Chuna, etc, but the Bee Venom therapy is the most common and effective. In this case, we used the Bee Venom therapy at cervical hyeopcheokhyeol for about 2 months to a patient who was diagnosed with disc herniation at Cervical 5-6, 6-7 and appealed weakness, limited elevation and abduction of the left upper limb. As a result, left upper limb disability was improved. Using the Bee Venom therapy at cervical hyeopcheokhyeol that are effective on movement disorders and neurological diseases of upper limb is an effective treatment to upper limb disability diagnosed with cervical disc herniation, and suggests the direction of the treatment to upper limb weakness and movement disorders diagnosed with cervical disc herniation.

Ossification of the yellow ligament (OYL) is a pathologic condition that causes spinal stenosis, which is a form of ectopic ossification. OYL causes compressive myelopathy and radiculopathy. Although the pathogenesis of OYL is still unclear, diffuse mechanical stresses and degenerative changes caused by extreme ranges of motion may be related to the development of OYL in young sportsmen. Here we report an interesting case of thoracic radiculopathy due to OYL in a 35-year-old male amateur judo player who was successfully treated with continuous thoracic patient controlled epidural analgesia and epidural adhesiolysis.

Spinal epidural hematoma is a rare complication associated with pain control procedures such as facet block, acupuncture, epidural injection, etc. Although it is an uncommon cause of acute myelopathy, and it may require surgical evacuation. We report four patients with epidural hematoma developed after pain control procedures. Two procedures were facet joint blocks and the others were epidural blocks. Pain was the predominant initial symptom in these patients while two patients presented with post-procedural neurological deficits. Surgical evacuation of the hematoma was performed in two patients while in remaining two patients, surgery was initially recommended but not performed since symptoms were progressively improved. Three patients showed near complete recovery except for one patient who recovered with residual deficits. Although, spinal epidural hematoma is a rare condition, it can lead to serious complications like spinal cord compression. Therefore, it is important to be cautious while performing spinal pain control procedure to avoid such complications. Surgical treatment is an effective option to resolve the spinal epidural hematoma.

An 8-year-old, shih-tzu female dog was referred due to neurological signs including paraparesis and back pain. On the complete blood count, hematologic analysis showed elevated leukocytosis. Serum biochemical analysis revealed elevated serum alkaline phosphatase concentration and C-reactive protein concentration. On the neurologic exam, the dog was suspected to have thoracolumbar myelopathy. On magnetic resonance imaging, there were masses within the spinal canal at L1-3 intervertebral disc space that were located dorsal to spinal cord. It was hyperintense on T1-, T2-weighted magnetic resonance images, Fluid-attenuated inversion recovery, and fat suppression images. The contrast-enhanced T1-weighted images showed no enhancement. The lesions were well circumscribed. The spinal cord was compressed and displaced ventrally by the mass. After removal of the masses via L1-L3 dorsal laminectomy, pyogranulomatous inflammation was confirmed by histopathological examination. Six months after surgery, the dog recovered uneventfully and remained fully ambulatory with no neurological deficits. This case demonstrates the utility of magnetic resonance imaging for the diagnosis of spinal canal pyogranulomatous inflammation.

Objectives & Methods: We investigated 28 books to study etiology and pathology of Son-Bal Jeorim. Result and Conclusion 1. The eiology of Son-Bal Jeorim is same as it of Bee Jeung(痺症). 2. Generally speaking, the cause of Bee Jeung was distributed Wind(風), Coldness(寒), Wetness (濕) of meridian. Bee Jeung can be devided into SilBi(實痺) and HeoBi(虛痺). In SilBi(實痺) there are PungHanSeupBi(風寒濕痺) and YeolBi(熱痺). In HeoBi(虛痺), there are GiHyeolHeoBi(氣血虛痺), EumheoBi(陰虛痺) and YangHeoBi(陽虛痺). 3. Son-Bal Jeorim belong to peripheral neuropathy in western medicine. 4. Syndrome of acute motor paralysis with variable disturbance of sensory and autonomic function, subacute sensorymotor paralysis, syndrome of chronic sensorimotor polyneuropathy, neuropathy with mitochondrial disease, syndrome of mononeuropathy or nerve plexusopathy. 5. Peripheral neuropathy is caused by carpal tunnel syndrome, diabetic neuropathy, uremic neuropathy, hepatic neuropathy, hypothyroid neuropathy, hyperthyroid neuropathy, neuropathy due to malnutrition, neuropathy due to toxic material, neuropathy due to drug, paraneoplastic neuropathy, hereditary neuropathy, etc. 6. Cerebral apoplexy, myelopathy, peripheral circulatory disturbance, anxiety syndrome cause symptoms of peripheral neuropathy

Spinal extradural arachnoid cyst (SEAC) is a rare disease and uncommon cause of compressive myelopathy. The etiology remains still unclear. We experienced 2 cases of SEACs and reviewed the cases and previous literatures. A 59-year-old man complained of both leg radiating pain and paresthesia for 4 years. His MRI showed an extradural cyst from T12 to L3 and we performed cyst fenestration and repaired the dural defect with tailored laminectomy. Another 51-year-old female patient visited our clinical with left buttock pain and paresthesia for 3 years. A large extradural cyst was found at T1-L2 level on MRI and a communication between the cyst and subarachnoid space was illustrated by CT-myelography. We performed cyst fenestration with primary repair of dural defect. Both patients' symptoms gradually subsided and follow up images taken 1-2 months postoperatively showed nearly disappeared cysts. There has been no documented recurrence in these two cases so far. Tailored laminotomy with cyst fenestration can be a safe and effective alternative choice in treating SEACs compared to traditional complete resection of cyst wall with multi-level laminectomy.

A 7-month-old female Bichon Frise, displaying neck pain and ataxia, was diagnosed with craniocervical junction abonormality (CJA), along with atlantoaxial subluxation. Surgical fixation of the atlantoaxial subluxation was performed, using cortical screws and bone cement, along with an odontoidectomy. After surgery, nonsteroidal anti-inflammatory medication was prescribed for pain control, and a loose bandage was applied to the neck. Mild ambulatory tetraparesis remained 1 week after surgery. Three weeks after surgery, the range of neck motion was near normal, and clinical signs had improved. CJA should be considered as a differential diagnosis in dogs with cervical myelopathy. Surgical stabilization using cortical screws and bone cement through a ventral approach can be successful in dogs with CJA and atlantoaxial subluxation.
