MRI of Primary Spinal Epidural Primitive Neuroectodermal Tumor: A Case Report
原發性脊椎硬膜上原始神經外胚層腫瘤之磁振造影影像：病例報告
摘要
原始神經外胚層腫瘤為高度惡性且在脊椎相當罕見。我們報告一18歲男孩之原發性脊椎原始神經外胚層腫瘤病例，腫瘤侵犯胸椎硬膜上區域伴隨脊髓壓迫。磁振造影在T1加權影像及T2加權影像上均顯示和脊髓相同訊號的病灶，並且在注射對比劑後顯示不均勻顯影。 原發性脊椎原始神經外胚層腫瘤之預後極差，雖然在脊椎發生原始神經外胚層腫瘤是極為罕見的情形，對於脊椎腫瘤的病人仍應該將它列入鑑別診斷。

Primitive neuroectodermal tumor (PNET) is highly malignant and extremely rare in the spine. We present a case with primary spinal primitive neuroectodermal tumor (PSPNET) which involved epidural space of thoracic spine with cord compression. Magnetic resonance imaging (MRI) showed an isointense epidural lesion on T1WI and T2WI. Heterogeneous enhancement following the administration of gadolinium is also noted. The prognosis of PSPNET is very poor. Even though PNET in spine is an extremely rare condition, it should be included in differential diagnoses for patients with spinal tumor.
