MRI results with mild disc desiccation c5-6 and C6-7. It says annular bulge and bony encroachment on right side of right neural foramen at c5-6. I had Chiari decompression, craniectomy and duraplasty 2008 and took out bottom part skull and c1/2. Now have terrible headache and neck pain. Brain MRI shows mildly predominant cisterns magna, mild amount of T2 signal of periventricukat and corona radiate white matter , tiny pineal cyst but no other mass. Focus of low gradient echo signal along posterior fall to right of midline likely benign calcification. Left more than right ethmoid sinus mucosal disease without acute sinus mastoid effusion. Small cyst found on sphenoid sinus.What does all this really mean? Is it related to my Chiari?
