By far the greater proportion of cases of cerebral thrombosis occur in the middle cerebral artery or its branches, resulting in the well known hemiplegia, with or without aphasia. Owing to the infrequency with which primary thrombosis of cerebral arteries other than the middle cerebral is encountered, the associated clinical syndromes are not generally familiar and accordingly may sometimes pass unrecognized.
