title: A case of spinal epidural haematoma during breath-hold diving.
abstract: Spinal epidural haematoma (SEH) is a rare condition usually the result of bleeding of the epidural venous plexus that might present with acute spinal cord compression. It is often due to traumatic events, but 'spontaneous' cases have been described, usually related to different predisposing conditions, such as coagulopathies. A 47-year-old male presented with severe frontal headache and intense cervical pain which developed during a protracted breath-hold spearfishing session. A cervical spine MRI performed 12 days after symptom onset showed a small epidural blood collection on the left side of the spinal canal, at the C7-T1 level. One week later, blood was no longer present and the asymptomatic patient was discharged. Protracted minor trauma (neck flexion) and repeated Valsalva manoeuvres might have played a role in the genesis of this event. The role of decompression sickness is discussed as well.
