Diagnostic contribution of routine cerebro-spinal fluid analysis during myelography

The laboratory summary sheets and patient charts concerning 500 consecutive myelograms were reviewed to see whether a routine cerebro-spinal fluid analysis at the time of a neuroradiological procedure made any significant diagnostic contribution. A relatively high frequency of abnormal findings was noted but in no case was significant clinical information obtained. Routine cerebrospinal fluid analysis during myelography does not on the basis of this study seem appropriate.
