Occult thoracic intradural extramedullary spinal canal lesions discovered by extending cervical and lumbar myelography.
We retrospectively reviewed the extended myelograms of 388 patients and identified two clinically occult intradural extramedullary lesions of the thoracic region of the spinal canal. Quality evaluation of the adjacent thoracic region can be quickly and simply performed at the time of lumbar or cervical myelography with the high volumes of relatively nontoxic water soluble intrathecal contrast agents allowed today. We recommend this screen to detect otherwise occult thoracic lesions.
