特発性脊髄硬膜外血腫の2例

Spinal epidural hematoma (SEH) is relatively rare, and the classical clinical condition is acute onset with back pain, followed by symptoms of nerve root or spinal cord compression.
We report two cases of spontaneous spinal epidural hematoma (two males). One was cervicothoracic hematoma on the ventral side of the spinal cord, the other was cervical hemotoma on the dorsal side. Magnetic resonance imaging (MRI) showed a high intensity lesion with T1-weighted and T2-weighted imagings. Operative decompression was performed for these cases. Because the cases were operated soon after the diagnosis, greater neurological recovery was obtained.
The critical factors for recovery after SEH are the operative interval and preoperative neurological deficits. Rapid diagnosis and emergency surgical treatment are very important for patients in SEH.
