We report a case of a spontaneous spinal epidural hematoma extending from T2 to T4 in a 21-year-old woman diagnosed by magnetic resonance imaging, and with complete recovery after immediate surgical treatment. Prognosis of spontaneous spinal epidural hematoma depends on two factors; severity of the neurologic deficit on admission, and interval from on set of initial symptom to surgery. Early diagnosis and prompt surgery are crucial to achieve the best neurological outcome and delay in the diagnosis and treatment causes permanent neurologic deficit.
