Recent MRI


So I had an MRI for a hematoma at the back of my head which is gone now. I had decompression surgery in 2015 but this new MRI report says my cerebellar tonsil is low lying located at the foramen magnum… Shouldn’t that been taken care of with my surgery in 2015?? Im confused and the doctor office is closed!


No. Decompression surgery doesn’t raise the tonsils, unless they were cut which is unusual. The surgery makes the space around them larger to improve fluid flow to help relieve symptoms. It’s normal after surgery for the tonsils to be in the same place


That makes more sense to me. Thank you for your response.
