Review of myelograms in evaluation of spinal lesions prior to advent of computed tomography (CT) scan in Ghana.

We retrospectively reviewed myelographic appearances of 2005 patients in ten years prior to advent of computed tomography (CT) scan in three major hospitals in Ghana. 877 (43.75%) were normal and 1128 (56.25%) were pathological. The lesions detected were spondylosis 321 (28.22%), disc herniation 272 (24.37%) trauma 172 (15.25%), Pott's disease 133 (11.79%), spinal tumours 101 (8.96%); Arachnoiditis 74 (6.56%) and spinal stenosis 46 (4.07%). Myelography still remains the examination of choice in the investigation of spinal lesions in the sub-region.
