[Cerebral infarction presenting pure motor monoparesis: diagnosis by diffusion-weighted MR imaging].
We studied 10 patients with acute ischemic cerebrovascular disorders presenting paralysis confined to one limb, unaccompanied by sensory signs(pure motor monoparesis, PMM) on diffusion-weighted MR imaging(DWI). DWI revealed fresh ischemic lesions in all patients, except for 2 cases of transient ischemic attack. On DWI, acute infarction in multiple lesions was identified, and small superficial lesions were clearly described. Superficial lesions were seen in 4 patients, and deep lesions were also seen in 4 patients. DWI is useful for lesion analysis in cerebral infarction with PMM.
