Radiology Cases of Atretic Cephalocele

MRI of atretic cephalocele
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.
