Cranial subdural migrating to lumbar subdural space in a toddler.

Migrated spinal subdural haematoma (sSDH) is a significantly uncommon finding. This case involves a paediatric patient representing after cranial trauma with new abnormal gait and leg pain who was found to have a migrated sSDH. Literature review for reported cases of pathogenesis theories, causes and management was performed and summarised in this report. The authors concluded that new abnormal gait and leg pain in a paediatric patient with previous cranial trauma is an indication for spinal MRI if migrated subdural haematoma is suspected. Non-surgical management is generally tolerated, and steroids can be trialled for radiculopathy if clinically indicated.
