Intramedullary spinal cord metastases are very rare. Patients with breast cancer as the primary source of intramedullary spinal cord metastases tend to do better than other types of cancer. We report the very unusual case of a woman with breast cancer who had two separate episodes of intramedullary spinal cord metastasis.

The authors describe a case of choriocarcinoma that metastasized to the cerebral cortex, vertebral body, and intramedullary spinal cord. A 21-year-old woman presented with sudden headache, vomiting and a visual field defect. Brain computed tomography and magnetic resonance examinations revealed an intracranial hemorrhage in the left temporo-parietal lobe and two enhancing nodules in the left temporal and right frontal lobe. After several days, the size of the hemorrhage increased, and a new hemorrhage was identified in the right frontal lobe. The hematoma and enhancing mass in the left temporo-parietal lobe were surgically removed. Choriocarcinoma was diagnosed after histological examination. At 6 days after the operation, her consciousness had worsened and she was in a state of stupor. The size of the hematoma in the right frontal lobe was enlarged. We performed an emergency operation to remove the hematoma and enhancing mass. Her mental status recovered slowly. Two months thereafter, she complained of paraplegia with sensory loss below the nipples. Whole spine magnetic resonance imaging revealed a well-enhancing mass in the thoracic intramedullary spinal cord and L2 vertebral body. Despite chemotherapy and radiotherapy, the patient died 13 months after the diagnosis.

목적 : 접형동에 발생하는 일차성 암은 매우 드물어 전체 부비동 악성종양의 $0.3\%$를 차지한다. 접형동암이 드물게 발생되므로 많은 환자들을 분석하여 얻은 치료결과나 생존기간의 통계가 지금까지도 보고되지 않았다. 이에 본원에서 치료를 시행했던 접형동암 환자 1예의 치료경과를 보고하고자 한다. 증례 보고 : 일부 증례보고들과 소수의 환자들을 대상으로 했던 연구들을 재검토한 한 보고에 따르면 2년 생존율이 $7\%$였다. 본 증례는 접형동암으로 진단된 후 지금까지 29개월동안 생존하고 있다. 또한 척수내 전이는 암환자에서 드문 합병증인데 본 증례에서는 접형동암으로 진단된 후 25개월 만에 갑자기 하지 마비증세와 배뇨곤란을 호소하여 흉추부위를 MRI촬영한 결과 척수내 전이성종양을 3번 4번 흉추부위에서 관찰할 수 있었고 척수공동증을 그 이하부위에 동반하고 있었다. 저자들은 접형동암환자에서 척수공동증을 동반한 척수내 전이소견을 보인 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

A 31-year-old man presented with acute onset of paraplegia. The patient's history was significant for thyroid carcinoma that had been treated 2 years earlier by thyroidectomy. A magnetic resonance imaging scan showed an enhancing intramedullary lesion at T7-8. Patient underwent surgical treatment and a tumor with hematoma was resected via posterior midline myelotomy. Postoperatively, the patient's motor weakness was improved to grade 3. The lesion showed typical histologic features consistent with papillary thyroid carcinoma. Early diagnosis and microsurgical resection can result in improvement in neurological deficits and quality of life of patients with an ISCM.

척수내 전이암은 암환자에서 매우 드문 합병증으로 증상이 있는 척수 전이암 중 $3.4\%$정도를 차지한다고 보고된 바 있다. 척수내 전이암 환자의 생존 기간은 매우 짧아서 2개월 이내인 경우가 대부분인데 그 이유는 신경학적으로 빨리 악화되고 뇌전이를 포함하여 여러 곳에 전이암이 동반되기 때문이다. 국내 문헌상 척수내 전이암에 대한 보고가 거의 없고 저자들이 경험한 두 증례는 서로 다른 임상 경과를 보였기에 문헌 고찰과 함께 보고하는 바이다. 원발암이 접형동암인 환자에서 척수내 전이암으로 인해 이차성 척수공동증을 동반한 증례는 세계 문헌상 세번째 증례이다. 한 증례는 증상이 서서히 진행되었고 척수에 방사선치료를 시행한 후 생존기간이 26개월이었고, 다른 증례는 증상이 매우 빠르게 진행되었고 생존기간이 훨씬 짧았다. 척수내 전이암도 신경학적 증상이 가역적인 상태에서 조기 진단이 내려진다면 더욱 효과적인 증상완화를 기대할 수도 있다.

폐암 환자에서 척수에 대한 신경학적 증상이 발생할 경우, 척수 수질 내로의 전이를 고려해야 하며, 조기 진단이 예후에 중요한 영향을 미칠 것으로 사료된다. 자기공명영상 검사는 이러한 병변의 진단에 매우 민감한 검사이나, 임상증상과 원발병변, 타 장기로의 전이 등을 함께 고려하여야 하며, 가능하다면 조직검사를 시행하여 진단할 수 있다. 본 예는 임상양상 및 방사선 검사에 의해 매우 드문 비소세포 폐암의 척수 수질내 전이로 판단된 경우이기에 보고하는 바이다.

The first case of intracranial metastases of a cervical intramedullary low-grade astrocytoma without malignant transformation in adult is presented in this report. Seven years ago, a 45 year-old male patient underwent biopsy to confirm pathologic characteristics and received craniocervical radiation and chemotherapy for a grade II astrocytoma in the cervical spinal cord. Two years later, posterior fusion was necessary for progressive kyphosis in the cervical spine. He was well for approximately 7 years after the primary surgery. Two months ago, he presented with partial weakness and incoordination with gait difficulty. MRI Scan demonstrated multiple small lesions in the cerebellar vermis and left hemisphere. After suboccipital craniectomy and posterior cervical exposure, the small masses in the cerebellar vermis and hemispheres were excised to a large extent by guidance of an intraoperative navigation system. The tumor at the cervical and brain lesions was classified as an astrocytoma (WHO grade II). When a patient with low-grade astrocytoma in the spinal cord has new cranial symptoms after surgery, radiaton, and chemotherapy, the possibility of its metastasis should be suspected because it can spread to the intracranial cavity even without malignant transformation as shown in this case.

An intramedullary spinal cord metastasis (ISCM) rarely develops in systemic cancer but is indicative of a poor prognosis. A 56-year-old man was admitted due to weakness of the lower extremities. He had received radiotherapy 3 months prior for a brain metastasis that had developed 1 year after achieving a complete response from chemotherapy for extended stage small cell lung cancer. Although the brain lesion had improved partially, ISCM from the cervical to lumbar-sacral spinal cords, which was accompanied by a leptomeningeal dissemination, was diagnosed based on magnetic resonance imaging of the spine and cerebrospinal fluid cytology. Finally, he died of sudden cardiac arrest during treatment. This is the first case of ISCM involving the whole spinal segments. Physicians should be aware of the subsequent development of ISCM in lung cancer patients with a previously known brain metastasis who present with new neurological symptoms.
