Unilateral Upper Cervical Cord Infarction: A Report of Two Cases with Mild Neurological Symptoms Accompanying a Small Ischemic Lesion Detected by Brain MRI

Figure 1

Magnetic resonance imaging (MRI) of spinal infarctions in two cases. The lesion for case 1 is presented in (a–e). (a) Thin-section coronal diffusion-weighted imaging (DWI), showing a high-intensity lesion of the cervical spine (arrow). (b and c) 3D fast imaging employing steady-state acquisition; MRI showing an upper cervical lesion. Axial (b) and sagittal (c); MRI showing a small, high-intensity lesion (arrows) at the level of the C2/3 intervertebral disc. (d) Axial, T2-weighted image of the cervical cord, examined 5 weeks after onset. (e) MR angiography of case 1, showing no apparent dissection of vertebral arteries. The MRI findings of case 2 are presented in (f–h). (f) Thin-section, coronal DWI and (g) axial DWI, demonstrating a high-intensity lesion (arrows) in the upper cervical cord. (h) T2-weighted axial image, showing a high-intensity lesion (arrow) in the right lateral funiculus at the level of the C1 vertebra.
