Spontaneous spinal subdural hematoma with spontaneous resolution

STUDY DESIGN: Single patient case report. OBJECTIVES: To present and discuss a case of spontaneous spinal subdural hematoma that was not associated with coagulation abnormality. SETTING: Seoul National University Hospital, Seoul, Korea. METHODS: Clinical and radiological magnetic resonance imaging follow-up of the patient between August 1997 and December 1998. RESULTS: The hematoma was initially extensive, ranging from T5 to L3. However, it resolved spontaneously with the subsequent development of an adhesive arachnoid cyst. CONCLUSION: Even though urgent surgical decompression is necessary in most cases of spinal subdural hematoma, conservative management could be an option in cases with rapid resolution of the neurological deficit.
