The result of the recent survey regarding cervical myelography by using a C1–2 puncture published by Yousem and Gujar is an important contribution to the neuroradiologic practice. The authors’ excellent work demonstrates the rationale in an effort to maintain the existing skills, even requiring certain skills. For a long time, we have practiced the lateral cervical approach with intrathecal pun...

myelography is a diagnostic procedure to indicate spinal defects. after the inception of new means of spinal cord imaging, use of myelography has been limited. since there are contraindications for other modalities in some patients, we have to use myelography. the most common complication of myelography is post myelography headache (pmh). many methods have been proposed to alleviate the pain. i...

Cervical radiculopathy is a disease process marked by nerve compression from herniated disk material or arthritic bone spurs. This impingement typically produces neck and radiating arm pain or numbness, sensory deficits, or motor dysfunction in the neck and upper extremities. Magnetic resonance imaging or computed tomographic myelography can confirm neurologic compression. The overall prognosis...

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. ...

Eleven patients with spinal canal block from metastatic epidural tumor, documented with Pantopague myelography, were given an additional injection of up to 5 cc of air. This technique forced contrast material past the block in 10 of 11 cases. It failed in one case in which symptoms had been present for 19 days. Air injection allowed visualization of more cephalad lesions and defined the superio...

There are many difficulties associated with the localisation of the symptomatic segment in patients presenting with cervicobrachial pain with no evidence of impaired conduction in the nerve root. Ancillary radiological investigations such as myelography, epidural phlebography, and epidural myelograms are of unreliable diagnostic value. However, discography can be of value if the technique descr...

Three cases of multiple spinal canal meningiomas are presented, bringing the total number of documented cases in the American literature to nine. While the exact incidence of multiple spinal meningiomas is difficult to determine, their possible occurrence warrants careful myelographic examination of the whole spinal canal, particularly if multiple clinical levels are present. When a complete bl...

sence of descent of the cerebellar tonsils or dural enhancement. Given the proper clinical setting, the ancillary findings of CSF hygroma, epidural venous collections, paraspinous fluid collections behind the C1-C2 level, and intracranial and extracranial venous dilatation are clues to the diagnosis. If one remembers that the epidural space is a gutter within which extrathecal CSF can travel lo...
