BOOK REVIEW Neurogenic tumor의 종류 및 치료
발생빈도 Neurogenic tumor는 종격동의 가장 흔한 원발성 종양 전체 종격종양 및 종격낭 중 20~35%
병리소견  후종격에서 가장 빈발 Intercostal nerve와 sympathetic chain에서 가장 흔히 발생 from intercostal nerve : neurofibroma, neurilemoma, neurofibrosarcoma from Sympathetic chain : ganglioneuroma, ganglioneuroblastoma, neuroblastoma
Dumbbell tumor Neurogenic tumor의 약 10%에서 종양이 intervertebral foramen을 통해 척수를 침범
임상양상 및 진단 소견 대부분 chest x-ray에서 우연히 발견 주위 조직에 대한 기계적 압박 때문에 증상이 생길 수 있음 Brachial plexus를 침범하는 경우 Pancoast’s syndrome을 일으킬 수 있음 목의sympathetic chain 침범하는 경우 Horner’s syndrome을 일으킬 수 있음 Dumbbell tumor의 약 60%에서 척수압박 증상이 나타남. 보통 척수내 종양을 먼저 절제한 뒤 후종격 부분의 종양을 절제
종류별 특징 및 치료 Schwannoma Neurogenic tumor중 가장 흔한 종류로 20~40대 사이에 빈발 Schwann’s cell에서 유래하며 encapsulation이 잘되어 있음 절제 후의 예후가 아주 좋음
Neurofibroma Nerve cell과 sheath 성분 모두를 포함 Encapsulation이 잘 형성되지 않고 불규칙하게 배열된 방추상 세포로 구성됨 전체 신경성 종양의 10% 미만 절제 후의 예후가 아주 좋음
Neurosarcoma 인슐린 같은 물질을 분비하여 간헐적인 저혈당 증세를 보일 수 있음 빨리 자라고 주위의 장기를 침범하는 경우가 많아 진단시 이미 절제가 어려운 경우가 많음 절제가 불가능한 경우레는 예후가 아주 나쁨
Ganglioneuroma 양성종양으로 소아에서 가장 흔한 neurogenic tumor 피낭이 잘 형성되어있고 절제 후 예후는 아주 좋음 Neuroblastoma Retroperitoneum에서 빈발하는 악성도 높은 종양 10~20%에서 종격동에서 원발성으로 발생 대부분 소아에서 발생하며 3세 이전에 주로 생김 침범 범위에 따라 절제만을 시행하거나 방사선요법/화학요법을 수술적 절제와 병행함
Paraganglioma Pheochromocytoma 종격종양의 1% 미만 대부분 paravertebral sulcus에서 발생하지만 중종격에서 생길 수 있음 악성빈도는 adrenal gland 이외에서 발생할때 높음 카테콜아민을 분비하여 고혈압을 일으킬 수 있음. 수술절제가 최선의 치료

  1. Neuroblastoma – sympathetic origin, HR, BP
  2. 2.6x1.8 cmright paravertebral extrapulmonary mass at the lovel of T7-8-> r/o fibrous tumor of the pleura, neurogenic tumor or other mesenchymal origin mass
  3. T7-8 level의 right paravertebral area에 2.6x1.8cm 크기의 oval mass가 있음. Extrapulmonarylocation하는mass로 pleura, posterior mediastinalmass의 가능성이 모두 있음. Fibrous tumor of the pleura, neurogenic tumor 혹은 다른 mesenchymal origin tumor가능성이 모두 있고 noncontrastscan으로 내부성상은 알 수 없음. 또한 2009.06.12 abdomen CT와 비교해서 크기변화 없어보여 benign lesion일 가능성이 높음.
  4. most likely nerutogenic tumor arising from tight 7thingtercostal nerve root(schwannoma?)
  5. Most likely neurogenic tumor arising from right 7th intercostal nerve root (schwannoma>neurofibroma) anteroinferiro aspect of right 7th rib- size: 2.6x 2 x 1.8 cm (transverse x vertical x AP dimension) - no definite association with neural foramina and spinal canal. -T2 intermediate dot like signal intensities with back ground T2 high signal intensity is noted, suggesting fascicular sign of schwannoma - internal T2 high T1 iso signal intensity with peripheral enhancement is seen, suggesting internal necrosis.
