Spontaneous regression of cervical disc herniation is a rare, and such reports are few. A 39 year-old woman complained of severe neck pain associated with tingling and numbness of right upper extremity. The MRI of the cervical spine revealed a posterior disc extrusion at the C4-C5 level in the right para-central location. The patient was treated with conservative management without any surgical treatment. The patient's symptoms were significant improvement. After two years later, we performed follow-up cervical MRI that revealed significant spontaneous regression of the C4-C5 intervertebral disc extrusion.

3.Low Grade Myofibroblastic Sarcoma Occurred in the Scalp.
Journal of Korean Neurosurgical Society 2015;58(4):385-388
Low-grade myofibroblastic sarcoma (LGMS) is a rare sarcoma with myofibroblastic differentiation. LGMS has a propensity for local recurrence and is associated with a low risk of metastatic spread. A 26-year-old man presented with a 12-month history of a slow growing palpable hard mass in the right parietal scalp. Enhanced CT scan of head showed a 3x4 cm sized well-defined and heterogeneously enhancing scalp mass. The patient underwent excision of the tumor. The histological and immunohistochemical features were consistent with a LGMS. We performed re-operation for remnant tumor removal after diagnosis. After 14 months of surgery, the patient was well-being state.

Upward migration of the peritoneal catheter of a subgaleo-peritoneal (SP) shunt and coiling into the subgaleal space is an extremely rare complication of a SP shunt. A 32-year-old male patient visited our hospital presenting with a large skull defect due to a prior craniectomy performed elsewhere. The patient underwent a cranioplasty with methylmetacrylate, but subsequently developed progressive pseudomeningocele and subgaleal cerebrospinal fluid (CSF) collection. The patient underwent CSF diversion via a SP shunt. After SP shunting, the pseudomeningocele disappeared completely. Six months later, the patient presented with progressive scalp swelling. Skull X-ray showed migration and coiling of the distal catheter of the SP shunt. The patient was treated by removing the entire shunt catheter and the dura was covered with a subgaleal flap. We would like to report our experience with a very rare complication of subgaleo-peritoneal shunting.

5.Twelve Contiguous Spinous Process Fracture of Cervico-Thoracic Spine.
Korean Journal of Spine 2014;11(3):212-213
The clay-shoveler's fracture is an isolated avulsion fracture of the lower cervical or upper thoracic spinous process. Among them, multiple spinous process fractures are very rare. We present 34-year-old male patient who have multiple spinous process fractures with twelve contiguous levels of cervico-thoracic spine (from C4 to T8) after motorcycle accident. This case is multiple isolated spinous process fractures with good clinical outcome.

Chemotherapy offers palliative treatment to patient with advanced nonresectable hepatoma. The usefulness of systemic chemotherapy is limited becaused of serious side reaction and low concentration of drug at tumor. Butthis problem may be overcome by intraarterial infusion. Nonsurgical percutaneous hepatic arteiral catheterizationwas done in 21 patients with primary hepatoma, and infusion chemotherapy was done in 19 patients who were successful in catherization. The results were as follows; 1. Selective catheterization of hepatic artery proper,common hepatic artery, and celiac artery were seccessful in 4, 9 and 4 patients, respectively. The success rate ofselective catheterization is 80.9% including celiac artery among 21 patients with hepatoma. 2. Simple catherization method was applied in 14 patients, and catheter exchange and Loop methods were applied in 2 and 1patient respectively. 3. Complications related to catheterization, such as infection and bleeding on punctured site, intimal injury and dislodgement of catheter were not serious. 4. Drugs were well tolerated without serioustoxicity or complication. 5. 3 patients showed objective response and median survival time of treated patients is 2.5 months.

The authors describe a case of aneurysmal bone cyst of a thoracic vertebra. A 34-year-old woman presented with posterior neck and upper back pain. Radiological examination demonstrated an aneurysmal bone cyst involving the posterior elements of the second thoracic vertebra. The spinal cord was compressed severely also. Satisfactory results were obtained after complete resection of the lesion.

Choroid plexus carcinomas are extremely rare in adults. They can behave aggressively and their optimal management is uncertain. A 35-year-old woman was admitted with an episode of loss of consciousness. Magnetic resonance imaging showed a homogeneously enhancing mass in the trigone of the right lateral ventricle. Detailed examinations found no evidence of an extraneural primary focus. She underwent total removal of the tumor. Pathological diagnosis was confirmed as a choroid plexus carcinoma. She is doing well eight months after surgery.

OBJECTIVE: The aim of this study was to evaluate the microanatomy and histological features of the central myelin in the root exit zone of facial nerve. METHODS: Forty facial nerves with brain stem were obtained from 20 formalin fixed cadavers. Among them 17 facial nerves were ruined during preparation and 23 root entry zone (REZ) of facial nerves could be examined. The length of medial REZ, from detach point of facial nerve at the brain stem to transitional area, and the thickness of glial membrane of central myelin was measured. We cut brain stem along the facial nerve and made a tissue block of facial nerve REZ. Each tissue block was embedded with paraffin and serially sectioned. Slices were stained with hematoxylin and eosin (H&E), periodic acid-Schiff, and glial fibrillary acid protein. Microscopy was used to measure the extent of central myelin and thickness of outer glial membrane of central myelin. Thickness of glial membrane was examined at two different points, the thickest area of proximal and distal REZ. RESULTS: Special stain with PAS and GFAP could be differentiated the central and peripheral myelin of facial nerve. The length of medial REZ was mean 2.6 mm (1.6-3.5 mm). The glial limiting membrane of brain stem is continued to the end of central myelin. We called it glial sheath of REZ. The thickness of glial sheath was mean 66.5 microm (40-110 microm) at proximal REZ and 7.4 microm (5-10 microm) at distal REZ. CONCLUSION: Medial REZ of facial nerve is mean 2.6 mm in length and covered by glial sheath continued from glial limiting membrane of brain stem. Glial sheath of central myelin tends to become thin toward transitional zone.
