The sagittal T2-weighted image (a) shows high signal intensity in the cervical spinal cord predominantly in its anterior aspect. The axial diffusion weighted imaging (b) shows high signal intensity in these areas. The axial apparent diffusion coefficient maps (c) show low signal intensity in the same locations. The sagittal T2-weighted image (d) shows partial resolution of high signal intensity at the location corresponding to (a)

C2 to C5. The signal changes in diffusion weighted imaging (DWI) and apparent diffusion coefficient map in the same region were indicative of acute infarction [Figure 1a-c]. Computed tomographic angiography, echocardiography, and laboratory evaluation for coagulopathy, including prothrombin G20210A gene mutation revealed unremarkable findings. Follow-up MRI performed 3 months after presentation showed partial resolution of the previous abnormal signal intensity [Figure 1d].
