My 20 yr. old son had a mri done with contrast. When I viewed a side view I noticed a black round spot on the back of his head above the brain stem. Can you give me any indication as to what this may show? It looks like there should be a noticeable lump protruding from the back of his head, although this is not the case. Any info would be appreciated.
Hello, The reporting of MRI involves viewing images acquired in various planes (vertical, horizontal etc.), with various settings (T1, T2 etc.). The appearance of same structure may vary greatly in different sequences (like white vs black). So it may be difficult to comment on the MRI from the description you have given. Consult your radiologist who has seen all the images. Also, the reason for which MRI was done will put things in perspective. Good luck.
