Foot drop – Common entity, uncommon aetiology

Foot drop is defined as the weakness of the tibialis anterior muscle and is frequently accompanied by weakness of the extensor hallucis longus and extensor digitorum longus. Dural arteriovenous (AV) fistula present mainly as progressive myelopathy, though it can also appear as amalgam of upper and lower motor involvement signs. Digital subtraction angiography is the definitive radiological procedure in the pre-treatment evaluation of vascular malformation. Treatment modalities include surgical resection or angiographically guided embolisation of malformation. We are reporting a case of spinal AV fistula presenting as unilateral foot drop, which showed significant improvement following the neuro-radiological intervention. Here, we report a rare presentation of spinal AV fistula as foot drop, showing good recovery following glue embolisation.
