The symptomatic debut was pain and paresis in all episodes. On all occasions, a lesion compatible with acute spinal subdural hematoma was diagnosed by magnetic resonance imaging (MRI). All episodes were treated conservatively with corticosteroids and immunosuppressants. The patient presented complete neurological recovery in the first two episodes. A mild residual left lower limb paresis remains after the last one. Follow-up MRI was performed after all episodes, and no focal intraspinal lesions were detected.
