Two Cases of Acute Epidural Hematoma with Spontaneous Recovery.

Most presenting symptoms associated with acute spinal epidural hematoma develop abruptly with spinal paralysis and require early diagnosis and decompression surgery. However, we exper ienced two cases of acute spinal epidural hematoma with spontaneous recovery.A 70-year old man was admitted to our hospital with complete paralysis. Thoracic spinal epidural hematoma was demonstrated with MR imaging. Emergency decompressive surgery was taken into considerative, but was not performed because of his rapid improvement. The second case was a 20-year-old man who complained of backache 5 days after a traffic accident. Lumber spinal epidural hematoma was observed on MR imaging. His symptoms spontaneously recovered completely 15 days after the onset.In this paper, we report these two cases in addition to our review of the literature.
