Abstract
THE CLINICAL diagnosis of occlusive cerebrovascular disease is usually based on a history of an abrupt or stuttering onset of focal cerebral dysfunction, excluding seizures, with some subsequent recovery. Although it has been known for many years that intracranial mass lesions, such as neoplasms, may occasionally produce an acute onset of lateralizing cerebral signs,1 the frequency with which this may occur has only recently been suggested.2-7 Several arteriographic studies of large numbers of patients with a clinical picture of occlusive cerebrovascular disease have now been published. The purposes of this communication are to collect the reported incidences of mass lesions from these studies and to add some personal observations of 252 patients who were carefully selected to fit the clinical criteria of occlusive cerebrovascular disease. Materials and Methods The 252 patients are part of a previously described study.8 Certain criteria for the selection of patients in this
