RESUMO
Objective To summarize the clinical features and treatment for the patients with acute spontaneous spinal epidural hematoma.Methods We retrospectively studied the causes of hemorrhage,clinical presentation,MR images,diagnosis and therapy in 8 cases operated in recent years.Results All patients had no specific cause with semilunar space occupying mass in posterior of the spinal canal on MR imaging.All patients were decompressed as early as possible,7 of them operated within 24 hours since the onset recovered well and the another operated after 50 hours because of misdiagnosis recovered poor.Conclusions MRI is the optimal choice for the diagnosis of acute spontaneous spinal epidural hematoma.Early diagnosis and decompression of spinal cord is crucial to neurological function recovery.
