This individual has three distinct, albeit to some degree related conditions: 1) meningoencephalocoele which resulted in gliosis of the frontal lobe which in turn resulted in 2) seizures. 3) demyelination, presumably multiple sclerosis given the presence of quiescent lesions on the first scan, seems harder to reconcile with the former, however incidence of MS is known to be higher in patients with head injury, so probably there is increased risk also in individuals with other cranial insults.
