Axial computed tomography image near the vertex on admission showing a hemorrhage and a peripheral low-density area (a). Axial bone window computed tomography image near the vertex revealing no fracture (b). Axial T2*-weighted magnetic resonance image clearly revealing cerebral contusions in the bilateral parasagittal region near the vertex (c)

Computed tomography (CT) of the brain revealed a subarachnoid hemorrhage, subdural hematoma, and contusions in his basal frontal lobes and superior frontoparietal lobes [Figure 1a and b]. Axial T2*-weighted MRI revealed contusions in both basal frontal lobes and bilateral parasagittal regions [Figure 1c].

Magnetic resonance imaging (MRI) of his spine revealed cervical spinal canal stenosis and lumbar spondylolisthesis; however, these lesions could not account for the pure motor paralysis of both legs [Figure 2].
Coronal (a) and axial (d) fluid-attenuated inversion recovery magnetic resonance images acquired on admission showing white matter lesions in the bilateral precentral gyri. These lesions were exacerbated 2 weeks after admission (b, e) and subsequently decreased by 7 weeks (c, f)

Axial, coronal, and sagittal fluid-attenuated inversion recovery (FLAIR) MRI images clearly demonstrated white matter lesions in the bilateral precentral gyri [Figures 3a and d]. Coronal and axial FLAIR MRI image at that time revealed areas of high intensity in bilateral precentral gyri that were broader than those observed on the initial MRI [Figures 3b and e]. At this time, the total size of the lesion on FLAIR MRI was significantly reduced [Figures 3c and f].
