Metrizamide is a non-ionised, water soluble, and completely absorbable contrast medium which can be used to demonstrate all sections of the spinal canal. The previous strict separation between water soluble, ionised media for the lumbal canal and oily media for the lumbosacral junction as well as the thoracic and cervical canal is no longer necessary. Experience in 110 patients shows that if a suitable concentration is chosen all segments of the spinal canal can be adequately investigated using the lumbal route. The application of contrast media via a lateral cervical entry or suboccipital puncture was not necessary in a single case. Side effects in the form of adhesive arachnoiditis were not observed.
Myelographic changes after spinal operation are often difficult to interpret especially with regard to the differentiation between arachnoiditis and recurrent disc prolapse. The radiological appearances using iophendylate (Myodil) and the distinguishing features are discussed and illustrated.
The data on clinical and electroencephalographic examination of 19 patients are presented. The patients developed facial hemiatrophy after they had sustained ganglionitis of the superior cervical sympathetic ganglion, stem encephalitis, trifacial neuralgia (neuritic stage), tumours of the Gasserian ganglion and syringobulbia. A pathogenetic relationship between the development of symptomatic facial hemiatrophy and lesions of the vegetative and somatic apparatus in the cerebral (mesencephalotruncal area) and extracerebral (superior cervical sympathetic ganglion) structures of the nervous system is noted.
