The purpose of this study is to present an analysis of 245 cases of lesions of the cerebral vessels in which the diagnosis was proved at necropsy in order to determine the significant findings in the history and examination that will aid in the differential diagnosis between cerebral hemorrhage and cerebral thrombosis.
The average physician rarely attempts to differentiate between these types, and the majority of cases of cerebral vascular lesion are indiscriminately labelled "cerebral hemorrhage." This is true despite the difference in the symptoms, the signs and especially the prognosis of these conditions. Also, with the more recent application of surgical treatment1 toward the relief of cerebral hemorrhage, it is evident that the treatment becomes even more divergent than that previously advocated. The academic exercise of localizing the lesion, which is so intriguing to the neurologist and internist, must be supplemented by an ability to differentiate the types
