Kernspintomographie der Perineuralzyste

: It may be difficult to differentiate between symptomatic perineural cysts, arachnoidal cysts, meningoceles, neurinomas and other cystic masses within the spinal canal and spinal foramina. Therefore the impact of MRI on the differential diagnosis of these lesions is discussed on the basis of 15 cases with perineural cysts, 1 case of an arachnoid cyst, 2 cases of meningoceles and 2 cases of neurinomas. The problem of fluid characterisation by the use of special MR measurements is emphasised.
