we report the case of a 29 year-old woman who presented a symptomatic intracranial subdural hematoma developing shortly after spinal anesthesia. the patient was fully conscious at clinical onset, and thus we treated her conservatively with an epidural autologous blood patch and close neurological observation. given the clinical improvement the possibility of surgery was discauded in agreement with the neurosurgical team. most cases of subdural hematoma appearing after spinal anesthesia are treated with surgery. in the present case the subdural hemorrhage was detected at our hospital 20 days after the anesthetic procedure, and given the excellent state of consciousness, we choosed a conservative management.
