Cordectomy for syringobulbo-myelia with sleep apnea secondary to a spinal extramedullary tumor: case report.
The case of a 40-year-old man with syringobulbo-myelia secondary to an unresectable spinal extramedullary tumor is described. Fifteen years previously, the patient had undergone a laminectomy of T8 through T12 for a "benign" spinal cord tumor at another hospital and had become paraplegic; the tumor (neurinoma) had been neglected for 12 years. Magnetic resonance imaging demonstrated a large thoracolumbar spinal tumor with syringobulbo-myelia. Polysomnography showed central-, peripheral-, and mixed-type sleep apneas. After the failure of an attempted syringoperitoneal shunt, cordectomy at the level of T6 was performed with a good result. The mechanisms of the formation of syringomyelia and sleep apnea secondary to a caudal spinal extramedullary tumor are discussed.
