My observations of this MRI are that there is nothing blatant. That is, there is no obvious excess of fluid above the brain, the corpus callosum is slightly flattened though; the cerebellar tonsils are a little low but not herniated, this possibly might cause problems according to head position; the pituitary isn’t flattened, which would suggest perhaps that if any raised intracranial pressure exists, it is intermittent.
Due to time constraints, I haven’t taken any measurements of angles etc but I would suggest that a neutral, flexion and extension MRI study might be beneficial here (with there being obvious hypermobility in the child) to see if the distance between the Opisthion and the back of the Dens, is reduced, particularly when the head is in full flexion. Note – the Dens is the tip of the Odontoid – the ‘peg bone’ in neck; the Opisthion is at the back of the Foramen Magnum (i.e. hole in the bottom of the skull where the spinal cord comes through). This reduction in space may put subtle pressure on cerebellum, or brainstem, or anything else that exists within that space, altering cerebro-spinal fluid flow too. This could bring on any of the multitude of symptoms associated with that area.
An upright MRI may show a worsening state with regard to the amount of cerebellar tonsillar herniation, through the foramen magnum, which will exhibit as symptoms of Chiari 1 Malformation. So I would also suggest that if possible, the neutral, flexion and extension MRI study be taken in the upright position.
Hope some of this helps.
