Here, a 34-year-old male presented with a thoracic spinal dumbbell metastatic neuroendocrine carcinoma of unknown primary origin. Case Description: A 34-year-old male presented with 2 months of thoracic pain and progressive mid thoracic sensory loss. A post contrast thoracic MRI showed a dumbbell tumor localized between the T7 and T9 levels with extension laterally into the T7-T8 and T8-T9 foramina. The patient underwent a laminectomy for tumor resection following which his pain and gait improved. Histopathologically, the tumor demonstrated multiple rounded small cells with a Ki67 level around 30%, suggesting a malignant metastatic neuroendocrine tumor of unknown etiology. Conclusion: We successfully treated a 34-year-old male with a T7-T9 malignant spinal dumbbell neuroendocrine tumor of unknown etiology utilizing a decompressive laminectomy.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/86929218-b87a-413c-9d84-2fc6c91d4647/featured/hero-1781561361292.png","publishDate":"2022-05-13T00:00:00.000Z","doi":"10.25259/SNI_341_2022","categories":["Spine","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2022/05/11591/SNI-13-199.pdf"}
