Cervical myelographic findings of brachial plexus injury by trauma

Authors reviewed 50 cases of cervical myelography during 4 years and 5 months, from February, 1985 to July, 1989 at Department of Radiography, 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 predominant in male and the incidence was 50% in 3rd decade of the males. 2. Among the 50 patients, 11 were the peripheral type, which had symptoms but normal findings in cervical myelography and 39 were the central type, which were definitely abnormal findings in cervical myelography. 3. Cervical myelographic findings in the central type were divided into 5 groups. (all 39 cases) a. Obliteration of nerve root filling defect 39(cases) b. Pseudomeningocele. 32(cases) c. Narrowing 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 myelography 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
