Spinal neurenteric cyst results from the persistence of an abnormal communication between endodermal and ne-uroectodermal layer. Embryologically, neurenteric cyst is derived from endoderm that is fused with the developing notochord during the third week of gestation. It is a rare malformation that lead to spinal cord compression. The patient is 19-year-old male presented with chest pain, paresthesia and progressive weakness in his low extremities(grade II/II). Preoperative MR imaging revealed intradural extramedullary cyst with intracystic hemorrhage in T1 and T2 level that is ventrally located and compressed the spinal cord. Involved vertebral bodies were scalloped and fused. The cystic tumor were totally removed through costotransversectomy approach. Postoperatively, motor weakness of the low extremities were improved to the level of grade IV/V. And chest pain and paresthesia were gradually disappeared. Postoperative MR imaging showed the decompression of the thoracic spinal cord. Histologic examination revealed a ciliated columnar epithelial neurenteric cyst. The pre- and postoperative clinical, radiological features of a case of upper thoracic neurenteric cyst is described with review of literature.

Giant cell tumor (GCT) of the spine is a rare benign tumor, but can be aggressive and can exhibit a high local recurrence rate. Furthermore, GCT of the upper thoracic spine may pose diagnostic and management difficulties. Here, we report a rare case of GCT of the upper thoracic spine with soft tissue extension to the spinal canal. The patient was managed by decompressive laminectomy and posterolateral fusion followed by an injection of polymethylmethacrylate into the vertebral lesion. The patient recovered clinically and showed radiological improvement after surgical treatment without tumor recurrence at his last follow-up of postoperative 7 years. We present this unusual case of GCT and include a review of the literature.

Tumors of the central nervous system are common in the pediatric population and constitute the second most prevalent tumor type in children. Within this group, spinal cord tumors are relatively rare and account for 1 to 10% of all pediatric central nervous system tumors. We describe a very rare case of an intradural extramedullary spinal cord tumor with a subcutaneous mass and discuss its clinical presentation, pathogenesis, and treatment. A male infant was delivered normally, with uneventful development. At 16 days post-delivery, his family took him to a pediatrician because of a mass on his upper back. Magnetic resonance imaging of the thoracic spine revealed a well-demarcated soft-tissue mass with central cystic change or necrosis at the subcutaneous layer of the posterior back (T2-7 level). Another mass was found with a fat component at the spinal canal of the T1-3 level, which was intradural extramedullary space. After six weeks, the spinal cord tumor and subcutaneous mass were grossly total resected; pathologic findings indicated an atypical myxoid spindle cell neoplasm, possibly nerve sheath in type. The final diagnosis of the mass was an atypical myxoid spindle cell neoplasm. The postoperative course was uneventful, and the patient was discharged after nine days without any neurological deficit. We report a rare case of an intradural extramedullary spinal tumor with subcutaneous mass in a neonate. It is necessary to monitor the patient's status by examining consecutive radiologic images, and the symptoms and neurological changes should be observed strictly during long-term follow-up.

Objectives : This study was performed to evaluate the effects of root of Cibotii rhizoma(CR) ethanol extract on the tissue and neuronal damage of the spinal cord injury(SCI). Methods : SCI was induced by mechanical contusion following laminectomy of 10th thoracic vertebra in Sprague-Dawley rats. CR was orally given once a day for 7 days after SCI. Tissue damage and nerve fiber degeneration were examined with cresyl violet and luxol fast blue(LFS) histochemistry. HSP72(as neuronal damage marker), MAP2(as nerve fiber degeneration marker), c-Fos(immediate early gene), and Bax(pro-apoptotic molecule) expressions were examined using immuno-histochemistry. Individual immuno-positive cells expressing HSP72, MAP2, c-Fos and Bax were observed on the damaged level and the upper thoracic and lower lumbar spinal segments. Results : 1. CR reduced degeneration of nerve fibers and motor neuron shrinkage in the ventral horn of the lower lumbar spinal segment, but generally it did not seem to ameliorate the tissue injury following SCI. 2. CR reduced demyelination in the ventral and lateral funiculus of the lower lumbar spinal segment. 3. CR reduced HSP72 expression on the neurons in the peri-central canal gray matter adjacent to the damaged region. 4. CR strengthened MAP2 expression on the motor neurons in the ventral horn and on nerve fibers in the lateral funiculus of the lower lumbar spinal segment. 5. CR reduced c-Fos positive cells in the peri-lesion and the dorsal horn of the damaged level and in the ventral horn of the lower lumbar spinal segment. 6. CR reduced Bax positive cells in the peri-lesion and the dorsal horn of the damaged level and in the ventral horn of the lower lumbar spinal segment. Conclusions : These results suggest that CR plays an inhibitory role against secondary neuronal damage and nerve fiber degeneration. following SCI.

A 12-years-old female admitted to the hospital with the complaint of pain on the right upper chest area which persisted about 1 month prior to admission. $Caf{\acute{e}}$-au-lait spots of various size laying on a whole body and freckling on the axilla were found on physical examination. A huge mass was found on the plain chest X-ray and on chest MRI. The mass encroached thoracic spine, posterior rib, back muscles, and then into the neural canal and compressed thoracic spinal cord. On the 5th day of hospitalization, the patient complained tingling on the both legs and 2 days later, monoparesis on the right leg. Open thoracotomy and decompressive laminectomy was done to remove mass. Pathologic reports confirmed rhabdomyosarcoma, embryonal type.

복강내장을 지배하는 감각신경세포체 및 신경섬유의 표지부위를 관찰하기 위하여 복강내장을 부위별(위, 십이지장, 공장, 회장, 맹장, 오름결장, 내림결장)로 나누어 2.5% WGA-HRP $30{\mu}l$와 0.5% CTB $20{\mu}l$를 장막과 근육층 사이의 4부위에 나누어 주입하였다. 그 후 48-96시간의 생존시간이 경과한 후 뇌줄기, 척수신경절과 미주신경절에서의 감각신경섬유와 신경세포체의 표지부위를 면역조직화학 염색법과 HRP 조직화학 기법으로 관찰한 결과는 다음과 같다. 1. WGA-HRP에 표지된 감각신경섬유는 위와 맹장에서만 관찰되었으며, CTB에 표지된 감각신경섬유는 복강내장의 모든 장기에서 관찰되었다. 2. 복강내장을 지배하는 감각신경섬유는 뇌줄기내 좌우 고립로핵의 교질부, 교질부의 등쪽내측부, 교차연결부, 내측부, 넷째뇌실벽, 맨아래구역의 앞쪽경계 및 중심관의 등쪽 정중선인 교차연결부에 국소적으로 강하게 표지되었다. 3. 척수신경절에서 위 (stomach)에 분포하는 감각신경세포체는 좌우 관계없이 $T_2$에서 $L_1$까지 여러 신경절에 표지되었으며 이 중 좌우 $T_{8-9}$부위에 가장 많이 표지되었다. 4. 십이지장에서의 척수신경절에 표지된 감각 신경세포체는 좌우 $T_6-L_2$부위에 표지되었으나 다른 장기에 비하여 표지된 감각신경세포체의 수는 적었다. 5. 공장에서의 척수신경절에 표지된 감각신경세포체는 좌우 $T_6-L_2$부위에 표지되었다. 가장 많이 표지된 부위는 좌측 $T_{12}$ 부위였으며, 우측은 $T_{13}$ 부위에 표지되었다. 6. 회장에서의 척수신경절에 표지된 감각신경세포체는 좌우 $T_6-L_2$부위였다. 가장 많이 표지된 부위는 좌측에서 $T_{11}$부위였고, 우측에서 $L_1$부위였다. 7. 맹장에서의 척수신경절에 표지된 감각신경 세포체는 좌측은 $T_7-L_2$부위였으며 우측은 $T_6-L_1$부위였다. 가장 많이 표지된 부위는 좌측은 $T_{11}$이었으며, 우측은 $T_{11-12}$에 표지되었다. 8. 오름결장에서 척수신경절에 표지된 감각신경세포체는 좌측은 $T_7-L_2$부위에 표지되었고 우측은 $T_9-L_4$부위에 표지되어 좌우측 표지부위의 차이를 보였다. 가장 많이 표지된 부위는 좌측은 $T_9$이었으며, 우측은 $T_{11}$에 표지되었다. 9. 내림결장에서 척수신경절에 표지된 감각신경 세포체는 좌측은 $T_9-L_2$부위에 표지되었고 우측은 $T_6-L_2$부위에 표지되었다. 가장 많이 표지된 부위는 좌측은 $T_{13}$이었으며, 우측은 $L_1$에 표지되었다. 10. 복강내장을 지배하는 좌우 미주신경절에 표지된 감각신경세포체는 위에서 가장 많이 표지되었으며 위를 제외한 나머지 장기에서는 표지된 감각신경세포체의 수는 위에 표지된 수보다 적었다. 이상의 결과로 흰쥐의 복강내장을 지배하는 감각신경섬유의 뇌줄기내 표지영역은 좌우 고립로 핵의 교질부, 교질부의 등쪽내측부, 교차연결부, 내측부, 넷째뇌실벽, 맨아래구역의 앞쪽경계 및 중심관의 등쪽 정중선인 교차연결부였으며, 감각신경세포체의 표지영역은 미주신경절과 척수신경절 $T_2-L_4$ 부위였음을 알 수 있었다. 위를 제외한 나머지 장기들에서는 $T_6-L_4$부위에 표지되었으나 소장에서 대장으로 갈수록 가장 많이 표지된 부위는 원위부 가슴신경절에서 근위부 허리신경절쪽으로 이동하는 경향을 보였다.
