Following is the meaning;
straightening of the normal cervical lordosis which may be secondary to patient position or muscle spasm = Normal cervical spine is curved. Your spine is showing absence of this curve which is straightened. This straightening of the spine can also be due to positioning of the neck when you were lying on the table for MRI or due to muscle spasm.
minimal disc bulge/osteophyte complexex through c2-c-5 = the cervical spine has seven vertebrae which are numbered C1 to C7. Your C2 to C5 show mild disc bulging and new small bone growth (osteophyte), which are formed due to wear and tear. Disc is the tissue which acts as a cushion between the two vertebrae.
interveterbal levels mild narrowing of c5-c6 disc, small broad based disc protrusion/osteophyte complexex at c5-c6 with minimal impression upon the ventral aspect of the spinal cord. = There is a decreased space due to narrowing of the disc (again these changes are part of the wear and tear arthritis/osteoarthritis). There is a disc protrusion and new bone formation which is causing slight pressure on the front portion of the cord.
minimal central spinal stenosis,no significant neuroforaminal stenoses = there is minimal narrowing of the central part of the spinal cord. There is almost no narrowing where the nerves comes out (neuroforaminal).
incidential findings: subcenitmeter bilateral anterior and posteior cervical lymph nodes. = there are some lymph nodes which are called incidental finding because it was not done for the neck lymph nodes. These lymph nodes are not significant.
Overall these changes show only what is termed as minimal cervical spondylosis. This can cause pain in neck and shoulder pain with numbness and tingling in the arm due to the pinched nerves.
