Haemorrhage in the neuraxial region following spinal and epidural interventions is a rare and unexpected complication. Subdural haemorrhage is the most frequently occurring type. A 64-year-old male patient was admitted with complaints of severe headache and intermittent fever after 14 days of spinal anaesthesia and inguinal hernia operation. Neurological examination and systemic examination showed no features other than that for postural tremor. Cranial and spinal magnetic resonance (MR) imaging were requested for the differential diagnosis of the patient with secondary headaches. In MR, subacute subdural haemorrhage adjacent to the dura, limiting the posterior sulcus, and extra axial distance (not clearly distinguishable epidural-subdural distinction) along the entire spinal canal were detected. The patient who had no neurological deficit and no culture recruitment underwent conservative treatment. We would like to emphasize here that the coexistence of both intracranial subdural and spinal subdural-epidural haemorrhage can be seen as a complication after spinal anaesthesia, which has not been previously observed in the literature, along with the importance of headache after regional anaesthesia.
