RESUMO
One hundred consecutive patients with continuous, focal, polymorphic delta activity on EEG who were also studied by computerized cranial tomography (CT) were reviewed. Sixty-eight percent showed focal structural lesions on CT, with stroke being the most frequent etiologic factor. Tumors occurred less often and trauma more frequently than in previous studies. Convulsions were the most frequent cause of focal delta activity with a normal scan.

Subdural hematoma has rarely been implicated as a cause of chorea. We describe a case of chorea occurring several months after evacuation of a traumatic subdural hematoma. No other causes of chorea were found. In this case and one previously reported case, signs of tentorial herniation were present prior to surgery. Herniation may damage the basal ganglia, with resultant chorea.

The pupillary near response should always be evaluated when the light response is defective. We present a case of diabetic third-nerve paresis with concomitant light-near dissociation. Without careful evaluation of the near response, angiography would have been indicated to rule out a posterior communicating artery aneurysm. Pharmacologic and slit lamp testing can be used to verify light-near dissociation.
