"Additional 3D volumetric studies can be performed, and although time consuming to post-process may be more sensitive to subtle hippocampal volume loss. Gadolinium is not required 5. T2 relaxometry may also be useful in detecting cases of hippocampal sclerosis 5."

"Mesial temporal sclerosis should not be confused with the hippocampal sclerosis described in patients with limbic-predominant age-related TDP-43 encephalopathy (LATE)."
"The relationship, if any, of mesial temporal sclerosis with febrile seizures is controversial 12, and made more difficult due to the relative insensitivity of imaging and the difficulty in establishing whether a particular seizure was truly febrile. Up to one-third of patients with established refractory temporal lobe epilepsy have a history of seizures in childhood at the time of fever 3. However, follow-up of children with febrile seizures does not demonstrate a significantly increased incidence of temporal lobe epilepsy 3. One holistic opinion is that perhaps prolonged febrile seizures, such as febrile status epilepticus or FIRES, may be one, among several, risk factor for developing mesial temporal sclerosis 12."
