Sagittal T2 (above left) and sagital CISS (above right) MRI without contrast of the brain shows a fluid filled parietal lesion that contains meninges and that is connected by a short stalk to the dura. A persistent falcine sinus is present. Axial T2 MRI (below) shows the lesion to be in the midline.Sagittal T2 MRI of the brain shows in the subcutaneous tissue at the vertex of the skull a subgaleal lipomatis and cystic lesion in close approximation to a persistent falcine sinus.
