Neurogenic tumors of the mediastinum may have an intraspinal component connected by a narrowed segment of tumor in the intervertebral foramen,hence the descriptive term dumbbell.Recently we had an occasion to remove a dumbbell neurilemmoma in a 62 years old woman using an approach designed to allow wide posterolateral thoracotomy and concomitant laminectomy for a single stage removal of the entire tumor. The mass in the posterior mediastinum was discovered on routine chest roentgenography. CT scan demonstrated a dumbbell shaped soft tissue mass density compressing spinal canal but preserving spinal cord. There were no neurologic signs. A standard posterolateral thoracotomy incision was made to remove tumor mass and then T5 unilateral laminectomy has done by Neurosurgeon. 7 x 7 cm sized extrapleural neurilemmoma was round, cystic, soft mass which covered parietal pleural with invaded regional vertebrae. There was no postoperative neurological complication.

Objective : The authors reviewed 51 patients of spinal cord tumor located at the craniovertebral junction and high cervical area to determine which factors influenced resectability, complications, and postoperative outcomes. Methods : Radiological examinations, clinical data, and operation notes were evaluated, and additional follow-up information was obtained from outpatient examinations. The mean follow-up period was 3.5 years Results : The most common neurological findings were motor deficit(72.5%) and sensory change(47.1%). There was no clinical finding that is considered as pathognomic. Meningioma(18 cases, 35.3%) was the most common tumor in this region. Total removal was achieved in 45 patients. There was no surgical mortality. Immediate postoperative motor weakness were encounted in 11 cases(21.6%) which improved in long term followup except two patients. Conclusions : The location and relationship of the tumor to surrounding struncture determine its resectability. Postoperative results were related to the preoperative neurological status and pathological findings.

A 50-year-old man presented bilateral hypesthesia on and below the T6 dermatome and paresthesia. Magnetic resonance imaging (MRI) showed an intraspinal extradural tumor, which located from the 6th thoracic vertebral body to the upper margin of the 7th vertebral body, continuing dumbbell-like through the intervertebral foramen into the right middle thorax suggesting a neurogenic tumor (neurofibroma or neurilemmoma). With the patient in a prone position, we exposed and excised the tumor via a one stage posterior approach through a hemi-laminictomy of T6. Histologic examination showed a grade 1 meningothelial meningioma, according to the World Health Organization classification. Initially, we assumed the mass was a schwannoma because of its location and dumbbell shape. However, the tumor was actually a meningioma. Postoperatively, hypesthesia resolved completely and motor power of the leg gradually full recovered. A postoperative MRI revealed no evidence of residual tumor.

A schwannoma is a benign neurogenic tumor derived from Schwann cells. A rare case of a large painful schwannoma in the foot with metatarsal deformity was presented. Due to suspicion of malignancy, amputation had been recommended previously. We report on a rare case of a large forefoot schwannoma causing pain and paresthesia of the forefoot.

배경: 최근 종격동 내 양성 신경종에 대한 흉강경 수술은 비교적 보편적으로 시행되고 있다. 그러나 흉강 첨부에 위치하는 신경종에 대해서는 시야확보 및 접근의 어려움으로 인해 수술 도중 근처 신경 및 혈관 구조물의 손상으로 인한 합병증의 위험이 높다. 이에 저자들은 이 질환에서 흉강경 수술의 경험을 분석하고, 그 외 접근방법에 의한 수술을 비교하여 흉강경 수술의 적정성을 평가하고자 한다.대상 및 방법: 1996년 1월부터 2008년 9월까지 31예(남자 15명, 여자 16명)의 환자가 흉강 첨부에 위치하는 양성 신경종으로 절제수술을 시행 받았다. 3예의 환자가 von Recklinhausen씨 병 환자였다. 환자들의 나이는 8세부터 73세로 평균 45세였다. 종양 절제수술은 흉강경 수술이 14예, 측방 개흉술이 10예, 경부 및 경흉부 절개술이 6예 그리고 정중흉골절개술이 1예였다. 흉강경 수술(VATS군)과 그 외 침습적인 방법에 의한 수술(OP군) 결과를 의무기록을 통해 후향적으로 비교 분석하였다. 결과: VATS군에서 조직학적으로 신경초종(schwannoma) 9예, 신경섬유종(neurofibroma) 4예, 신경절신경종(ganglioneuroma)이 1예였다. 수술시간은 VATS군이 평균 113분으로 OP군의 153분 보다 적게 소요되었고, 흉관 거치기간 및 수술 후 입원기간도 VATS군이 각각 2일, 5일로 타군의 5일, 11일에 비해 짧았다(p<0.05). 흉강경 수술의 경우 개흉술로의 전환은 없었다. 술 후 합병증은 VATS군 경우 호너씨 증후군 2예 및 상완 신경총과 관련된 신경증상이 2예에서 발생하였고, OP군은 상기 증상이 각각 1예씩, 성대마비 증상이 1예, 그리고 비신경계 합병증이 2예에서 발생하였다. 흉강 첨부에 위치하는 양성 신경종의 흉강경을 이용한 절제수술 후 신경계 합병증 발생의 가장 의미 있는 위험인자는 비적출적 방법(non-enucleating method)에 의한 종양 절제인 경우였다(p=0.029). 결론: 흉강경을 이용한 흉강 첨부의 양성 신경종의 제거술은 타 방법에 비해 비침습적인 유용한 방법이다. 그리고 흉강경을 이용한 종양 적출술(enucleation)은 신경계 합병증 발생을 줄일 수 있는 방법이라고 생각된다.

The authors observed the clinical status of 29 patients with vocal cord paralysis caused by tumor from April, 1983 to September, 1993 at Department of Otorhinolaryngology, Yongdong Severance hospital, Yonsei University College of Medicine. The results were as follows: 1) In the kinds of neoplasms, the most frequent were lung Ca. with 13 cases(44.8%), followed by 8 cases by thyroid Ca., 3 cases by neurogenic tumor, 2 cases by mediastinum tumor, cervical esophagus Ca., tracheal Ca., glomus jugulare were 1 case each. 2) In sex distribution, there were 18 cases of males and 11 cases of females with the male to female ratio being 1.8:1. In age distribution, most of the cases(10 cases ; 34.5%) were in the 7th decade. 3) In chief complaints, most of the cases(17 cases : 58.6%) had hoarseness only and aspiration, stridor, dyspnea, cough, dysphagia were present in some cases. 4) In site of the paralysed vocal cord, 21 cases were in the left cord. 5 cases in the right cord and 3 cases in the both cords. 5) In the position of paralysed vocal cord, most of the cases(23 cases : 79.3%) were in the parmedian position.

신경종은 흔한 후종격동 종양으로, 신경집종은 종격동에 발생하는 신경종의 40%를 차지한다. 신경집종은 대개 무증상으로 우연히 발견된다. 일부 환자에서 종양이 신경이나 기도를 눌러서 증상이 나타날 수 있다. 그러나, 제1형 신경섬유종증이 아닌 단일 신경집종에 의한 자발성 혈흉은 매우 드물다. 저자들은 자발성 대량 혈흉을 동반한 단일 신경집종을 경험하여 보고한다.

Objective : Because the anatomical structure of the brachial plexus is very complex, surgical treatment of tumors in this region is challenging. Therefore, a lot of clinical and surgical experience is required for successful treatment; however, many neurosurgeons have difficulty accumulating this experience owing to the rarity of brachial plexus tumors. The purpose of this report is to share our surgical experience with brachial plexus tumor with other neurosurgeons. Methods : The records of 18 consecutive patients with brachial plexus tumors who underwent surgical treatment between January 2010 and December 2017 in a single institution were retrospectively reviewed. The surgical approach was determined according to the tumor location and size, and intraoperative neurophysiological monitoring (IONM) was used in most of cases to prevent iatrogenic nerve injury during surgery. In addition, to evaluate the differences in tumor characteristics according to pathologic diagnosis, the tumors were divided twice into two groups, based on two separate classifications, and statistical analysis was performed. Results : The 18 brachial plexus tumors comprised 15 (83.3%) benign peripheral nerve sheath tumors including schwannoma and neurofibroma, one (5.6%) malignant peripheral nerve sheath tumor, one (5.6%) benign tumor of non-neural sheath origin (neurogenic cyst), and one (5.6%) metastatic tumor (papillary carcinoma). The authors analyzed relationship between tumor size/location and tumor characteristic parameters such as age, size, right-left, and pathology. There were no statistically significant differences except a tendency of bigger tumor size in young age. Conclusion : For a successful surgical outcome, an appropriate surgical approach is essential, and the appropriate surgical approach is determined by the location and size of the tumor. Furthermore, applying IONM may prevent postoperative complications and it is favorable option for brachial plexus tumors surgery.

Radiological criteria such as smooth, sharply defined interface, obtuse angles between lesion and lung and intimate effect on mediastinal contents were usually used to differentiate mediastinal lesion from parenchymal lung lesion. Recently, we experienced a 60-year-old female presenting with anterior mediastinal mass with cavitation. Grossly it was proven to be peripheral lung cancer adjacent to mediastinum and microscopically it was squamous cell carcinoma. The gross pathological findings of surgical specimen were very well correlated with radiological findings. The unique location such as lung periphery and attachment to mediastinum led us to misdiagnosis of anterior mediastinal mass such as germ-cell tumor and neurogenic tumor.
