An interesting case of type 3 spinal cord arteriovenous malformation in a pregnant female presenting as compressive myelopathy

Arteriovenous malformation is described as an abnormal connection between arteries and veins bypassing the capillaries. Ten percent of the AV malformations of central nervous system are seen in the brain stem and spinal cord. There are 4 types of spinal AV malformations depending on the anatomic location. Type 3 or juvenile AVMs are seen in both extramedullary and intramedullary region. Type 3 AVM's are infrequently reported in the literature. This is a case of a 24 year old pregnant female who presented with a compressive myelopathy and diagnosed to have a type 3 spinal AV malformation on magnetic resonance imaging.
