A, B are MRI scanning axial T1 and T2 images, respectively, which show parallel separation of bilateral lateral ventricles, widening of the spacing between the bodies of bilateral lateral ventricles, and a lipoma (white arrowhead) at the lower margin of the cerebral falx, with a size of about 40mm*9mm, with high signal in T1 and T2. C is an axial DWI image; the lesion is seen without diffusion restriction. D is a sagittal T2 image; the septum pellucidum is not closed, and the corpus callosum is thinned in the sagittal position (white arrow)
