Spine vascular lesions from embryology to imaging findings review article with serial cases

Abstract

Spine vascular lesions like brain vascular lesions include spinal cord stroke, vascular malformation such as venous malformation or venous angioma, cavernous malformation, arteriovenous malformation or arteriovenous fistula. Embryogenesis of spinal vascular is the basic principle to understand the vascular malformation of the spine. This study aims to report serial cases with review of spinal vascular lesions. MR angiography techniques with contrast injection may reflect the direction of flow epidural veins to describe the site of arterial feeders. Serpiginous veins are commonly visible through the dorsal cord surface in MR myelography. The gold standard for diagnosing vascular malformation is Digital Subtraction Angiography (DSA). MRA helps to guide the location for DSA. Several cases are reported using MRA modalities and show the special location site of the spinal disorder.
