your daughter presents with signs of focal lesions in the brain through the seizures already as identified by the MRI
. Migraines and dizzy spells could be an indication of an increased intracranial hypertension
as it is called due to a mass effect. Cerebellar lesions are usually accompanied by gait and uncoordinated movements. My advice would be to have a neurosurgical review again with respect to a probable surgery or medical approach, but something has to be done to reduce the mass effective which already revealing itself clinically. Outcome in cerebellar surgery when done early and especially if tumour is benign is usually very good. Excessive delays could lead to continual raised intracranial hypertension and which may be detrimental.
Lesions on the skin I am afraid have nothing to do with the cerebellar tumour. A physician s review could help determine the nature and cause of these lesions.
Hope this helps,
Thanks and best regards,
