Epidural venous congestion represents the pathological dilatation of the spinalSpinal epidural venous plexus, and congestion or dilatation is typically a complication of other pathologies.
Clinical presentation
Radiculopathy caused by the dilated epidural veins is not uncommon 1.
Pathology
Several spinal and pelvic diseases can result in secondary epidural venous engorgement:
epidural lipomatosis
occlusion2inferior vena cavaagenesis (rare)35pelvic venous congestion due to external compression (e.g. distended bladder) 1
lumbar spinal canal stenosis 4
excessive CSF diversion (see overshunting-associated myelopathy)
vertebral artery occlusion 2
inferior vena cava agenesis (rare) 3
As the vertebral venous system is valveless, extraspinal venous congestion can rapidly involve these veins 1.
Radiographic features
MRI is the method of choice for imaging spinal epidural venous plexus pathology. Axial and sagittal plane T2-weighted sequences usually clearly demonstrate the engorged epidural veins and effacement of CSF spaces 1,2. The distended venous plexus should not be mistaken for mass, disc herniation, or arteriovenous fistulisation.
