<s>[INST] Hi,I am Meena Sheth. I was operated for cerivcal myelopathy in August, 2012. My latest MRI REPORT state that Diffuse bulges are seen from C3-4 to C6-7 levels, indenting the anterior subarachnoid space. The posterior longitudinal ligament is diffusely thickened.Pl do let me know in simple language what do you mean by above. [/INST] Hi, cervical myelopathy means - spinal cord in the region of neck is having issues. The diffuse bulge from c3-c4 to c6-c7 Levels means the disk between the two vertebrae is being pushed inside compartment (its slipped from normal position) which creates an indentation / grove like structure in spinal cord and compressing from the front side at separate locations between c3-c4 and c6-c7.  Posterior ligament is thickened - means the cover on the back portion of the vertebral column is thick.  Thanks. Hope it helps. Chat Doctor.  </s>
