Dural ectasia as an incidental finding on MRI in a patient with Marfan syndrome

A 48-year-old female with a history of Marfan syndrome and type A aortic dissection repaired with valve-sparing aortic root replacement and stable residual type B aortic dissection presented for surveillance MR angiography. At that time, dural ectasia was appreciated as an incidental finding with MRI showing high T2-weighted multilobar cerebrospinal fluid (CSF) spaces within the lower sacrum (figures 1 and 2). Anteroposterior diameter of the thecal sac was greater at the S1 level than at the L4 level, a defining feature of dural ectasia.1 Figure 1Axial T2-weighted MRI showing dural ectasia as indicated by arrow. Figure 2Sagittal T2-weighted MRI showing widening of dural space, indicative of dural ectasia, as indicated by arrows. Dural ectasia is commonly associated with Marfan syndrome and is best viewed with MRI. While the association is well...
