Spinal epidural hematoma after spinal manipulation therapy: Report of three cases and a literature review

Figure 3 Imaging examinations of case 3. A: First emergency magnetic resonance imaging (MRI) scan. T1-weighted image of the thoracic spine shows isometric-intensity spinal epidural hematoma at T1–2 (white arrow); B and C: First emergency MRI scans. T2-weighted image shows high signal intensity; axial T2-weighted image shows that the hematoma was in the posterolateral region (white arrow); D: Preoperative MRI suggests an enhanced hematoma signal (orange arrow); E: The hematoma decreased in size after conservative treatment (white arrow); F-H: After 72 h of conservative treatment, MRI showed that the hematoma worsened again (white arrow); I: The hematoma completely disappeared at the 3-mo follow-up (white arrow).
