We have recently experienced a third ventricular tumor from a 63-year old woman who presented with paraparesis, voiding difficulty and general weakness. Histopathologic study of the tumor was compatible with recently reported and newly termed chordoid glioma. Clinical behavior of the reported tumors were mostly benign but because of its very close proximity to the hypothalamus, some of the subtotally removed tumors recurred or some of the patients died of postoperative complications. The presenting patient regained normal leg power after removal of the tumor followed by ventriculoperitoneal shunt and discharged on her own feet.

A 34-year-old female patient was presented with leg and hip pain for 6 months as well as voiding difficulty for 1 year. Magnetic resonance imaging revealed a well-demarcated mass lesion at L2-3. The mass was hypo-intense on T1- and T2-weighted images with homogeneous gadolinium enhancement. Surgery was performed with the presumptive diagnosis of intradural extramedullary meningioma. Complete tumor removal was possible due to lack of dural adhesion of the tumor. Histologic diagnosis was clear cell meningioma, a rare and newly included World Health Organization classification of meningioma usually affecting younger patients. During postoperative 2 years, the patient has shown no evidence of recurrence. We report a rare case of cauda equina clear cell meningioma without any dural attachment.

Spinal extradural arachnoid cyst is uncommon and rarely cause neural compression. We report a rare case of severe cord compression due to septated spinal extradural arachnoid cyst. A 35-year-old woman has developed back pain 3 months prior to her visit, but recently motor weakness and urinary incontinence occurred. Magnetic resonance images showed an extradural cyst posterior to the cord, which was flattened and displaced from T12 to L2. Urgent decompressive laminectomy and cyst removal was performed. Histopathological examination confirmed that cyst wall was formed by nonspecific fibrous connective tissue without a single-cell layer of inner arachnoid lining. Motor weakness and voiding difficulty were recovered completely after operation.

Transsacral neurolytic block with 2.5ml of phenol in glycerine or bupivacaine was performed in 6 patients with malignant diseases and a patient with sphincter spasm of bladder due to spinal cord injury. Pain relief was satisfactory in all patints except one patient with very low pain threshold. In one patient, second transsacral neurolytic block alone was not sufficient because of widespread pain along distant metastasis of the malignant disease, although the first block was satisfactory. The complications include transient motor weakness(4), voiding difficulty(1), subarachnoid puncture(1), and epidural venous puncture(1), but they were all spontaneously recovered within a sbort period of time and did not give any limitation to the block.

A case of primary hyperparathyroidism due to parathyroid adenoma is presented. A 14 year-old male was admitted to the hospital comptaining of voiding difficulty. The intravenous pyelogram demonstrated a stone in the proximal one third of the left ureter and marked hydronephrosis of the left kidney. The Tc-99m sestamibi nuclear scan demonstrated a hot spot below the lower pole of the left lobe of the thyroid. Laboratory study demonstrated hypercalcemia (12.4 mg/dL) and elevated parathyroid hormone (143.67 pg/mL). A parathyroid gland located below the lower pole of the left lobe of the thyroid was excised. A parathyroid adenoma, consisting of mainly chief cells was found on pathologic examination. Postoperatively the patient had transient hypocalcemic symptoms, which resolved with administration of calcium preparation and vitamin D.

Guillain-$Barr{\acute{e}}$ syndrome (GBS) and acute disseminated encephalomyelitis (ADEM) are demyelinating neurologic disorders with different target organs. Although they share similar pathogenetic mechanism, reports of simultaneous occurrence of the 2 disorders are rare. A 2 year 6 month old girl visited our hospital for fever, cough, and general weakness. Although the muscle power of extremities showed mild weakness and voiding difficulty, initial deep tendon reflex of both knees and ankles was normal. A nerve conduction study to evaluate the weakness revealed the absence of F waves. Cerebrospinal fluid analysis demonstrated pleocytosis with lymphocyte predominance and elevated protein levels. Magnetic resonance imaging showed abnormal T2 hyperintensity in pons, medulla and spinal cord. Serum anti-GD1b antibody was positive. Based on clinical findings, laboratory findings, nerve conduction study, and neuroimaging, the diagnosis of GBS and ADEM was made. This is the first case of GBS accompanied by ADEM in Korea.

We report a case of pyogenic spondylitis on L2 and L3 with diffuse epidural abscess up to T4 to L3 and large psoas abscess. A forty-nine-year old male was presented with progressive back pain, left flank pain and ab-dominal distention, weakness of the both legs and voiding and defecation difficulty during last 2 months. Initially multiple coronal hemilaminectomies from T4 to T12 were done for the treatment of diffuse thoracic epidural ab-scess. Then second operation via left retroperitoneal approach was performed for lumbar spondylitis and psoas abscess on third day after initial operation. After removal and curettage of pyogenic psoas and epidural abscess and spondylitis (L2-L3), iliac bone grafting with Keneda instrumentation from L1 to L4 was done simultaneously. Postoperative course has been unevenful without recurrent infection. The literature on diffuse epidural and large psoas abscess with pyogenic spondylitis are reviewed and instrumentation for stabilization of pyogenic spondylitis is also discussed.

Spinal schwannomas are usually extramedullary intradural tumors and their intramedullary localizations are thought to be extremely rare. A 60-year-old woman complaining spastic quadriparesis, voiding difficulty and dyspnea was admitted. Her cervical MRI revealed an intramedullary mass in the cervicomedullary junction with multiple cyst which extended from lower cervical to C3 spinal cord. The mass showed a low signal on T1WI, high signal on T2WI with an wall enhancement. The patient underwent a suboccipital craniectomy and C1-2 laminectomy and the cystic tumor was totally removed through a midline myelotomy. The tumor was proved as an intramedullary schwannoma by pathologic examination. The Intramedullary presence of a tumor arising from the cells of the nerve sheath is unusual, because the central nervous system fibers do not contain the Schwann cell. There have been several hypotheses, but none has been accepted universally. This rare tumor is considered as a curable benign neoplasm, and an accurate intraoperative diagnosis and surgically total removal are essential.

Sacral nerve stimulation (SNS) is an effective treatment for bladder and bowel dysfunction, and also has a role in the treatment of chronic pelvic pain. We report two cases of intractable pain associated with cauda equina syndrome (CES) that were treated successfully by SNS. The first patient suffered from intractable pelvic pain with urinary incontinence and fecal incontinence after surgery for a herniated lumbar disc. The second patient underwent surgery for treatment of a burst fracture and developed intractable pelvic area pain, right leg pain, excessive urinary frequency, urinary incontinence, voiding difficulty and constipation one year after surgery. A SNS trial was performed on both patients. Both patients' pain was significantly improved and urinary symptoms were much relieved. Neuromodulation of the sacral nerves is an effective treatment for idiopathic urinary frequency, urgency, and urge incontinence. Sacral neuromodulation has also been used to control various forms of pelvic pain. Although the mechanism of action of neuromodulation remains unexplained, numerous clinical success reports suggest that it is a therapy with efficacy and durability. From the results of our research, we believe that SNS can be a safe and effective option for the treatment of intractable pelvic pain with incomplete CES.
