case_images: Magnetic resonance imaging carried out on day 2 of hospitalization of a 75-year-old man with spinal epidural hematoma caused by cervical massage using a commercial massage tool. The red arrows indicate hematoma. The posterior part of the spinal canal from C2/C3 to C3/C4 shows a T1-weighted iso-intensity (A) and a heterogeneous high-intensity and iso-intensity region on a T2-weighted image (B). C2/C3 is the thickest hematoma and the compression to the spinal cord is observed from the posterior.
