Periodic lateralized epileptiform discharges associated with subdural hematoma.
A case presenting with headaches, organic dysfunction with visual hallucinations, and incontinence of urine, all of two days' duration is described here.  EEG obtained on the fourth hospital day showed right-sided PLEDS and on the fifth hospital day a generalized seizure occurred.  The other clinical and laboratory data led to a diagnosis of bilateral subdural hematomas.  The patient recovered following surgical treatment.  No etiologic factor other than the subdural hematomas was found to explain the PLEDS.  Possible mechanisms of pathophysiology are discussed.
