목적: 원발성 및 전이성 척추종양의 치료는 해부학적 특성상 근치적 광범위 절제술이 용이하지 않다. 원발성 및 전이성 척추종양에 대해 다양한 수술을 시도하였으며, 그 중 전 척추절제술이 양호한 임상결과를 보여, 본원에서 원발성 및 전이성 척추종양으로 전 척추절제술을 받은 5례를 대상으로 임상적, 방사선학적 결과를 분석하였다. 대상 및 방법: 1997년 6월부터 2006년 1월까지 본원 정형외과에서 치료하였던 환자 중 전 척추절제술을 받고 추시 관찰이 가능했던 원발성 척추종양 1례와 전이성 척추종양 4례를 대상으로 하였다. 전이성 척추종양의 원발 병소는 신장암 2례, 유방암 1례, 원발 병소 불명의 선암 1례였다. 전 척추절제술의 임상적 평가 방법으로 동통과 신경학적 증상을 McAfee의 4 point scale과 VAS(Visual Analogue Scale), 및 Frankel 분류를 이용하여 관찰하였다. 술 후 3개월마다 반복적인 이학적 검사를 시행하였으며, 단순 방사선촬영으로 국소 재발 및 골유합, 합병증을 관찰하였다. 결과: 동통의 평가는 McAfee scale에서 술 전 평균 3에서 술 후 평균 1.6으로 감소하였고, VAS는 술 전 평균 9.2에서 1.6으로 감소하였다. 술 후 신경학적 결손은 Frankel 분류 C에서 D로 호전되었다. 추시기간 중 제 4요추의 전이성 선암 1례에서 국소 재발이 관찰되었다. 결론: 전 척추절제술은 척수 신경을 완전하게 감압시키고 골격통을 신속하게 감소시키며 생존 기간 동안 삶의 질을 높이는 유용한 술식이다.

Objective : The purposes of this study are to estimate postoperative survival and ambulatory outcome and to identify prognostic factors thereafter of metastatic spinal tumors in a single institute. Methods : We reviewed the medical records of 182 patients who underwent surgery for a metastatic spinal tumor from January 1987 to January 2009 retrospectively. Twelve potential prognostic factors (age, gender, primary tumor, extent and location of spinal metastases, interval between primary tumor diagnosis and metastatic spinal cord compression, preoperative treatment, surgical approach and extent, preoperative Eastern Cooperative Oncology Group (ECOG) performance status, Nurick score, Tokuhashi and Tomita score) were investigated. Results : The median survival of the entire patients was 8 months. Of the 182 patients, 80 (44%) died within 6 months after surgery, 113 (62%) died within 1 year after surgery, 138 (76%) died within 2 years after surgery. Postoperatively 47 (26%) patients had improvement in ambulatory function, 126 (69%) had no change, and 9 (5%) had deterioration. On multivariate analysis, better ambulatory outcome was associated with being ambulatory before surgery (p=0.026) and lower preoperative ECOG score (p=0.016). Survival rate was affected by preoperative ECOG performance status (p<0.001) and Tomita score (p<0.001). Conclusion : Survival after metastatic spinal tumor surgery was dependent on preoperative ECOG performance status and Tomita score. The ambulatory functional outcomes after surgery were dependent on preoperative ambulatory status and preoperative ECOG performance status. Thus, prompt decompressive surgery may be warranted to improve patient's survival and gait, before general condition and ambulatory function of patient become worse.

Primary pulmonary meningioma is an extremely rare disease. It is mostly benign and asymptomatic. This tumor shows the same cytohigstologic appearance as brain or spinal cord meninioma. It can be diagnosed as a primary pulmonary meningioma only if there is no evidence of metastasis from the brain or spinal cord meningioma. We experienced a case of primary pulmonary meningioma in a 60-year-old woman who had asymptomatic 2 cm-sized solitary pulmonary tumor in the right lower lobe. It is rather peripherally located. Fine needle aspiration cytology has suggested the possibility of either well-differentiated epithelial malignancy such as papillary adenocarcinoma or mucoepidermoid carcinoma or metastatic carcinoma such as from ductal carcinoma of the breast. Right lower lobectomy was performed. The tumor was bilobated and soild with yellowish color. pathologically it proved to be a primary pulmonary and solid with yellowish color. Pathologically it proved to be a primary pulmonary meningioma because there was no evidance of brain or spinal cord tumor. To the best of our knowledge this is the first case reported in Korea. We report this case with review of the literature.

Primary central nervous system (CNS) melanoma is a rare condition that accounts for only 1% of all melanomas. A 34-year-old Korean female presented with a two-month history of progressive weakness in both legs. Spinal magnetic resonance image (MRI) revealed a spinal cord tumor at the level of T4, which was hyperintense on T1-weighted imaging and hypointense on T2-weighted imaging. The intradural and extramedullary tumor was completely resected and diagnosed as melanoma. There were no metastatic lesions. At three years after surgery, the patient is still alive, with no evidence of tumor recurrence. We present the details of this case along with a comprehensive review of spinal cord melanoma.

목적: 척추전이의 자기공명영상 소견들 중 특정 원발성 암에 특이적인 소견들이 있는지 알아보고자 한다. 대상과 방법: 본 연구에서는 자기공명영상을 시행한 총 169개의 척추전이암 병변들 (56개는 폐암, 29개는 유방암, 20개는 대장암, 17개는 간세포암, 그리고 47개는 위암으로부터 기원)을 후향적으로 분석하였다. 각 병변의 크기, 위치, 침범 정도, 신호강도, 경계, 조영증강 양상, 그리고 골융해/골경화 특성들을 분석하여 원발성 암의 기원에 따라 차이가 있는지 보았다. 결과: 간세포암의 전이 병변들은 대장암을 제외하고는 (P=0.268) 다른 암에 비하여 크기가 유의하게 컸다 (P < 0.05). 경계가 좋은 병변은 폐암과 유방암에서 기원한 경우에서 더 흔히 관찰되었다 (P < 0.01). 간세포암을 제외한 모든 암에서 전이를 할 때 척추의 후부요소보다 척추체를 더 자주 침범하였다(P < 0.02). 대장암과 간세포암은 골외 침범을 더 자주 보였으나 통계학적 의미는 없었다 (P > 0.05). 간세포암과 위암의 전이병변들은 특징적인 조영증강 양상을 보였다. 결론: 일부 자기공명영상 소견들은 척추전이 병변이 어떤 원발성 암에서 기원한 것이지 예측하는 데 도움이 될 수 있다.

Objective : To identify the perioperative factors associated with instrument failure in patients undergoing a partial corpectomy with instrumentation (PCI) for spinal metastasis. Methods : We assessed the one hundred twenty-four patients with who underwent PCI for a metastatic spine from 1987 to 2011. Outcome measure was the risk factor related to implantation failure. The preoperative factors analyzed were age, sex, ambulation, American Spinal Injury Association grade, bone mineral density, use of steroid, primary tumor site, number of vertebrae with metastasis, extra-bone metastasis, preoperative adjuvant chemotherapy, and preoperative spinal radiotherapy. The intraoperative factors were the number of fixed vertebrae, fixation in osteolytic vertebrae, bone grafting, and type of surgical approach. The postoperative factors included postoperative adjuvant chemotherapy and spinal radiotherapy. This study was supported by the National Research Foundation grant funded by government. There were no study-specific biases related to conflicts of interest. Results : There were 15 instrumentation failures (15/124, 12.1%). Preoperative ambulatory status and primary tumor site were not significantly related to the development of implant failure. There were no significant associations between insertion of a bone graft into the partial corpectomy site and instrumentation failure. The preoperative and operative factors analyzed were not significantly related to instrumentation failure. In univariable and multivariable analyses, postoperative spinal radiotherapy was the only significant variable related to instrumentation failure (p=0.049 and 0.050, respectively). Conclusion : When performing PCI in patients with spinal metastasis followed by postoperative spinal radiotherapy, the surgeon may consider the possibility of instrumentation failure and find other strategies for augmentation than the use of a bone graft for fusion.

A 29-year-old woman had 1-month history of back pain radiating into lower extremities, motor weakness, and sensory abnormalities in both lower extremities. Contrast-enhanced spinal magnetic resonance imaging (MRI) revealed a homogeneously enhancing mass at the T12~L1 and several intradural enhancing nodular lesions at L2~S1. Tumor resection surgery was performed and following histological examination showed that the tumor satisfied the diagnostic criteria for atypical choroid plexus papilloma (CPP). To find primary tumor sites, contrast-enhanced brain MRI, whole spine MRI, and PET-CT were carried out and additional lesions were detected at the fourth ventricle, right cerebellum, and upper thoracic spinal cord. This is a very rare case of metastatic atypical CPP that involves brain, upper thoracic spinal cord, and cauda equina with initial manifestation of radicular symptoms without clinical signs of primary brain lesion.

Leiomyosarcoma of the mediastinum and primary leiomyosarcoma of the spine are exceedingly rare. In most cases, spinal leiomyosarcoma is metastatic. In this report, we describe the case of a 58-year-old man who presented with a large leiomyosarcoma of the posterior mediastinum that extended into the adjacent spinal canal. The tumor was completely resected from the mediastinum, but only subtotally removed from the spinal canal because the spinal mass had tightly invaded the spinal cord. Because the patient's postoperative condition was poor, no adjuvant radiotherapy or chemotherapy was administered. He expired 3 months after the surgery due to relapse; the spinal and mediastinal tumor remained at the preoperative size.
