İnvaze tümörlerin tek seansta güvenli bir şekilde spinal ve torasikkomponentinin birlikte çıkarılması gerekir. Bu lokalizasyondaki tümörlerinspinal kanal invazyonunun olup olmadığının direkt ve indirekt bulguları,ameliyat öncesi çektirilen bilgisayarlı tomografi (BT) ve manyetik rezonansgörüntülemesi (MRI) ile detaylı olarak değerlendirilmelidir. Çalışmamızda,kliniğimizde opere ettiğimiz bu tür tümörlerdeki tanı ve yaklaşımımızınsunulması amaçlanmıştır.Gereç ve Yöntem: Nörojenik tümör nedeniile opere ettiğimiz tüm hastaların klinik bilgileri retrospektif olarak analizedildi.Bulgular: Çalışmaya aldığımız 35 hastanın19’u erkek 16’sı kadındı ve yaş ortalaması 40 yıldı (dağılım: 19-71). Hastalarınsadece 5’inde (%14) operasyon öncesi semptom mevcuttu. Tümör boyutları 2,1 cm ile 17 cm arasında (ortanca 6,2)idi. Hastaların 7’sinde (%20) radyolojik olarak spinal kanal invazyonu olduğubelirtildi. Laminektomi gerektiren dumbbelltipteki 6 hasta ile birlikte hepsi komplet olarak rezeke edildi. İnvazyongösteren vakalardaki lezyonlar beyin ve sinir cerrahi uzmanı ile birlikteyapıldı. Ortalama takip süresi 48 ay (3 ila 72 ay) idi. Bir hastada ameliyatsırasında tamir edilen serebrospinal sıvı kaçağı ile postoperatif kalıcıolmayan spinal hasar meydana geldi ve 4 ayda düzeldi. Mortalite gözlenmedi.Sonuç: Ameliyat öncesinde, nörojenik dumbbell tümör teşhis edilmezse, sadeceintratorasik kısmının çıkarılması, kalıcı spinal hasara neden olabilir. Spinal kanalıincelemek için MRI kritik öneme sahiptir. Preoperatif invazyon tespitedildiğinde tek seansta sinir cerrahisi ekibi ile birlikte tümörün daha güvenlirezeksiyonu mümkündür.</p></abstract>

                            <p>Aim: Approximately 10% of posterior mediastinal neurogenic tumors invade thespinal canal. Safe removal of these tumors requires single-stage combinedneurosurgical and thoracic operations. Meticulous radiological preoperativeexamination with computed tomography (CT) and magnetic resonance imaging (MRI)is obligatory for assessing direct or indirect signs of spinal canalinvolvement. Hereby, we reviewed our clinical experience of preoperativediagnostic and therapeutic approaches in these types of tumors.Materials and Methods: Clinical files of all patients undergoing surgicalresection at our institution for a neurogenic tumor located at the posteriormediastinum were reviewed retrospectively.Results: The mean age of the 35 patients was 40 years (range 19-71), including 19males and 16 females. Preoperativesymptoms were present in five patients (14%). Tumorsize was ranging from 2.5 to 17 cm (median 6.2). Preoperative radiologicalexamination revealed spinal canal involvement in seven (20%) patients. Allpatients were performed complete resection, including an additional laminectomyin six cases of dumbbell-type. Intraforaminal portion was resected by theneurosurgeon. Mean follow-up period was 48 (range 3-72) months. Majorcomplication of postoperative cerebrospinal fluid leakage, detected and treatedintraoperatively, with non-permanent spinal cord injury was seen in 1 patient,fully recovered in 4 months postoperatively. No mortality occurred.Conclusion: If a dumbbell neurogenic tumor is not recognized and only theintrathoracic portion is resected, it may cause permanent spinal cord injuryand neurological problems. Spinal MRI is crucial to examine the spinal canal. Ifspinal canal invasion is detected preoperatively, a single-stage and saferesection with neurosurgical team may be possible.</p></trans-abstract>
