Although computed tomographic (CT) myelography and magnetic resonance imaging (MRI) are used for assessing lumbar disc herniations (LDH), they cannot provide images when patients are standing or walking, whose CT myelograms and MRI images show only slight disc bulging. The purpose of this study was to evaluate the usefulness of upright myelography. We examined by myelography in both an upright ...

The patient was a 50-year-old woman who had had frequency of urination and numbness of the left side of the trunk for a few years. Neurologic examination showed slight anisocoria (right > left), asymmetry of muscle stretch reflex (right > left) in both upper and lower extremities, hypalgesia and thermohypesthesia of the left side of the trunk, and hypopallesthesia in the right lower extremity. ...

The increased incidence of motor vehicle accidents during the past century has been associated with a significant increase in brachial plexus injuries. New imaging studies are currently available for the evaluation of brachial plexus injuries. Myelography, CT myelography, and magnetic resonance imaging (MRI) are indicated in the evaluation of brachial plexus. Moreover, a series of specialized e...

Six cases of syringomyelia associated with intramedullary tumor were examined by metrizamide myelography and delayed computed tomography. All cases showed opacification of syringomyelic cavities 7-24 hr after myelography. This finding suggests that metrizamide can pass through the cord substance from the subarachnoid space into a syrinx cavity in noncommunicating types of syringomyelia. It supp...

A case report of transverse myelitis and optic neuritis is presented in which the latter occurred following a myelogram with iopamidol. The literature relating to neurotoxicity of contrast agents is reviewed, and it is suggested that the optic neuritis may have been a neurotoxic effect
