BILATERAL choking of the optic disk has been demonstrated to be caused at times by high-lying tumors of the cervical portion of the spinal cord, particularly those that encroach on the foramen magnum. However, the development of choked disks secondary to tumors in the low thoracic, lumbar and sacral regions of the spinal cord has not been reported, so far as we know. In a brief review of the literature, we could not find any reported case in which choked optic disks were associated with a tumor of the spinal cord located below the second thoracic segment. In his recently published text, Walsh1 does not mention any such case. Recently, one of us (J. G. L.) operated for tumor located low in the spinal cord on two patients in whom the clinical findings, and particularly the presence of bilateral choked disk, suggested, in addition to the lesion of the
