Normal 0 false false false EN-US X-NONE AR-SA Normal 0 false false false EN-US X-NONE AR-SA CSF spaces comprise all intracerebral ventricles, spinal and brain subarachnoid spaces, such as cisterns and sulci, and the central canal of the spinal cord. Research of CSF flow and its disorders began as early as 1913 by Dr. Walter Dandy of John Hopkins university.[1] First by experimental animals studies and then in 1919 more studies as pneumoventriculography yielded more information about CSF pathways and its abnormalities. Multiple congenital and...

Normal 0 false false false EN-US X-NONE AR-SA Patients: Prospective study was conducted on 140 patients presented by ventriculomegaly or dilated CSF spaces. The patients were categorized into 7 groups according to the primary site of obstruction, type of the lesion or malformation. Conventional MRI imaging with 3D –CISS were included routinely as part of the examination followed by dynamic phase contrast sequence (magnitude and phase contrast cine images) that was tailored according to the suspected site of obstruction or malformation. Time-SLIP sequence was used...

Normal 0 false false false EN-US X-NONE AR-SA The study included 140 patients. Group 1: Obstructed ventricular foramina. (Fig. 3,4,5,6) Nine patients were presented by headache. Seven of them showed thin webs obstructing foramen of Monro. While, two patients showed fourth ventricle outlet obstruction by webs and subarachnoid synechiae at the basal CSF cisterns with obliteration of the foramina of Luschka. If one of the fourth ventricular outlets appeared obstructed, the hydrocephalus was categorized as non-communicating. Identification of obstructive pathologic processes at any level through...
