Postictal cortical restricted diffusion and edema

Case contributed by Assoc Prof Frank Gaillard

Presentation

Protracted seizures.

Patient Data

Age: Adult

Gyral high DWI signal and high T2 signal on the left, in the setting of protracted seizure activity probably represents post-ictal change. 

Case Discussion

It is difficult to be certain that this merely represents postictal change, although this is most likely the case. Alternative diagnoses include encephalitis or even subacute ischemia. Demonstrating rapid resolution confirms the diagnosis (not available in this case).
