BB Sharma, Sandeep Sharma, Priya Ramachandran and Sarita Jilowa

Arteriovenous malformation (AVM) of the spine can present with different symptomatology. This depends upon the region of involvement and with the background of underlying angioarchitectures. AVM occurrence at filum terminale needs special reference as it is not covered under any classifications. Arteriovenous fistula (AVF) can remain undiagnosed because of the location and the way of its presentation. Rodesch et al. has found as 3.2% prevalence in one of their series of arteriovenous shunts management. Selective Digital subtraction angiography (DSA) is required to find out the arterial feeder for its guidelines to the appropriate management. We present 42- years old male who presented with long standing low backache with numbness in both lower limbs. Contrast Magnetic Resonance Imaging (MRI) investigation of Lumbosacral spine diagnosed as a case of having arteriovenous fistula of filum terminale.
