Dural ectasia is a radiological finding characterised by enlargement of the dura in the spinal cord, especially in the lower lumbosacral regions.
Pathology
The connective tissue weakness in the underlying condition is thought to lead to expansion of the dura from the pulsatile flow of the cerebrospinal fluid. The lower regions are affected because that is where subarachnoid pressure is highest. Dural ectasia can result in bony erosions and/or meningoceles and herniation of nerve root sleeves can occur.
The cardinal underlying condition is Marfan Syndrome where it is present in 60% of individuals. However it can also be seen in neurofibromatosis type 1, Ehlers-Danlos syndrome, Loeys-Dietz syndrome, osteogenesis imperfecta, acromegaly, and ankylosing spondylitis. It can also occur post trauma, post surgery, and from tumours.
Clinical Features
It is also associated with back pain and lumbar radicular pain and radiculopathy. The bony erosions and meningoceles can cause constipation and/or incontinence. The meningoceles can be anterior to the sacrum and be palpable as an abdominal mass. Other findings include spondylolisthesis, scoliosis, and fractures.
