Research overview:
Eight cases with pure motor monoparesis (PMM) exhibiting only upper limb monoparesis due to cerebral infarction were studied using MRI diffusion highlighted images. Strong paralysis was observed at a distal site in all cases. Most responsible foci captured by the diffusion highlighted images were small foci of 15 mm or less. Multiple foci were observed in 6 cases. Internal carotid stenosis was suggested in 4 of 8 cases, and an embolic mechanism was suggested in 2 cases. It was emphasized that the responsible focus is captured by DWI as early as possible and an onset mechanism is examined to select the therapy for secondary prophylaxis of cerebral infarction.
