MR demonstrates marked dilatation of fourth, third and lateral ventricles, without trans-ependymal edema. Midsagittal thin slices T2DRIVE images show membranous occlusion at the level of the foramen of Magendie.
Case Discussion
Non-communicating hydrocephalus due to membranous obstruction of Magendie's foramen is a rare condition. In this case, the patient has a history of bacterial meningitis a few years ago and probable cause of membranous occlusion is a sequela of arachnoiditis.
