His dictation “abnormal developmental safe posterior elements of the C2 vertebral body with deformity of the lamina of C2 which extends through medially into the central spinal canal. There is mild impression on the posterolateral aspect of the cervical cord on the left. This creates a mild left sided stenosis of the spinal canal” is hard to understand. If we take out the term “safe”, you have an abnormal bony protrusion that projects into the canal at C2 causing minor narrowing of the canal. There is no evidence of cord injury or significant compression.
It would be quite unlikely that this is causing your “pain/weakness etc neck & left arm for 4 months”. There must be more finding from different levels from your MRI report. Please paste them here.
