Intramedullary spinal cord tumors are generally operated on by using the posterior approach. However, the posterior approach may not be suitable for a tumor in the anterior part of the spinal cord. In this report, we describe a case of a cervical intramedullary tumor that was successfully removed by using the anterior approach.
A 48-year-old woman presented with lower cranial nerve disturbance and motor weakness of the upper extremities. Magnetic resonance imaging revealed a large extensive syrinx and an intramedullary enhanced tumor at the C6 level. The tumor was located at the left of the anterior part of the spinal cord.
Based on these findings, the anterior approach was used in performing a corpectomy of C5 and C6. The tumor was highly vascular and was resected without resulting in any operative deficits. The pathological diagnosis was hemangioblastoma.
The present case suggests that the anterior approach is an important option among surgical approaches to the intramedullary tumor in cases in which the tumors are small in size and are located in the anterior part of the cervical cord.
脊髓髓内肿瘤一般采用后路手术。然而，后路手术可能不适用于脊髓前部的肿瘤。在本报告中，我们描述了一例通过前路手术成功切除的颈髓内肿瘤病例。
一名48岁女性出现下颅神经功能障碍和上肢运动无力。磁共振成像显示在C6水平有一个大的广泛空洞和一个髓内强化肿瘤。肿瘤位于脊髓前部左侧。
基于这些发现，采用前路手术进行C5和C6椎体次全切除术。肿瘤血供丰富，切除后未导致任何手术缺损。病理诊断为血管母细胞瘤。
本病例表明，对于肿瘤体积小且位于颈髓前部的髓内肿瘤，前路手术是手术治疗方法中的一个重要选择。
