Spinal cord MR findings were abnormal in 14 of 30 patients.The abnormal MR can be divided into group A,in which one segment was involved(8 patients), and group B,in which more than one segment was involved(6 patients).In both groups there were 2 patients with enhancing lesions.Enhancement was less homogeneous in the group B patients.Enhancement did not change with increased length of lesion.At follow-up,the diagnostic categories of the patients were multiple sclerosis(8 patients),encephalomyelitis(1 patient), viral myelitis(3 patients),and myelopathy of unknown case(18 patients). After the episode of acute transverse myelopathy,in 4 of 8 patients in group A and in 4 of 5 patients with normal spinal MR but abnormal brain MR findings clinical signs of multiple sclerosis developed.In no patients in group B did multiple sclerosis develop.The final diagnoses for the 4 patients with gadolinium-enhancing spinal lesions were myelopathy of unknown cause(2 patients),multiple sclerosis(1 patient)and viral myelitis (1 patient). |
