Metachronous brain and intramedullary spinal cord metastases from nonsmall-cell lung cancer: A case report

AbstractA 44-year-old man had a brain tumor secondary to lung adenocarcinoma and underwent craniectomy to remove the brain tumor. After postoperative whole-brain radiation therapy, he underwent pneumonectomy followed by chemotherapy, mediastinal radiotherapy, and target therapy for lung cancer. Thirty-six months after the initial brain surgery, he suffered from neck pain and right upper limb numbness that rapidly progressed to upper extremity weakness and paralysis in 2 months. Magnetic resonance imaging demonstrated an intramedullary spinal cord lesion at the C4 level. Laminectomy and gross intramedullary tumor removal were performed. The patient’s neurological function improved after the operation. Nevertheless, 4 months after the intramedullary tumor removal, he began to show multiple metastases. Unfortunately, the patient died from respiratory failure 8 months after diagnosis with intramedullary spinal cord metastasis. In this case, early diagnosis and aggressive surgical treatment combined with postoperative radiotherapy and chemotherapy might have provided this patient with a prolonged survival and better quality of life
