Authors reviewed 50 cases of cervical myelography during 4 years and 5 months, from February, 1985 to July,1989 at Department of Radiology, Wonkwang University Hospital to analyse myelographic findings of traumatic brachial plexus injury with symptoms and signs and to discuss literature. The results were as follows: 1. Brachial plexus injury was predominent in male and the incidence was 50% in 3rd decade of the males. 2. Among the 50 patients, 11 were the peipheral type, which had symptoms but normal findings in cervical myelogarphy and 39 werethe central type, which were definitely abnormal findings in cervical myelography. 3. Cervical myelographic findings in the central type were devided into 5 groups.(all 39 cases) a. Obliteration of nerve root filling defect. 39(cases) b. Pseudomeningocele. 32(cases) c. Narowing of ipsilateral subarachnoid space. 31(cases) d.Diverticulum. 4(cases) e. Tracking of dye down the axillary sheath. 1(cases) 4. The most large numbers of pseudomeningoceles in cervical myelograpy were shown for two and in each case, the most multiple developing numbers of pseudomeningoceles were identified for four, that happened in one case. 5. In brachial plexus injury,there were two the most large involving numbers among the nerve roots, and in each involving nerve root, C7 was most common.
