"Ivy sign" on fluid-attenuated inversion-recovery images in childhood moyamoya disease.

M Maeda1, C Tsuchida.   

Abstract

We report on MR studies of a 15-year-old girl with moyamoya disease in whom diffuse leptomeningeal enhancement ("ivy sign") was revealed by fluid-attenuated inversion-recovery (FLAIR) and contrast-enhanced imaging. We speculate that the mechanism behind this enhancement is caused by a retrograde slow flow of engorged pial vasculature via leptomeningeal anastomosis. Nevertheless, it remains unknown whether the precise source of a high signal on FLAIR images is attributable to pial vessels themselves or congested thickening of the leptomeninges or both.
