Section 1 Submit Findings CB1046 Findings Axial Non Contrast CT or MR There is evidence of increased size of all vents (lateral, 3rd, 4th) for age indicating external hydrocephalus. Yes No There is evidence of specific ventricular obstruction at the level of the 3rd ventricle and/or the foramen of Monroe (including hyperintense colloid cyst on T1-w). Yes No There is evidence of specific ventricular obstruction at the level of the cerebral aqueduct. Yes No There is evidence of specific ventricular obstruction at the level of the 4th ventricle. Yes No There is evidence of early (hyperacute) obstructive hydrocephalus affecting only the anterior temporal horn configuration and expansion of the hypothalamic-segment, 3rd vent. Yes No There is evidence of grade 1.0/4 to grade 1.6/4 acute obstructive hydrocephalus. Yes No There is evidence of grade 1.8/4 acute obstructive hydrocephalus likely with impending incisural herniation. Yes No There is evidence of grade 2/4 acute obstructive hydrocephalus with downward central incisural herniation (displacement of supratentorial structures into the tentorial hiatus). Yes No There are primary imaging features of elevated intraventricular CSF pressure (subependymal edema, tightened appearance of the ependymal surface, upward bowing the lamina terminalis, downward bowing the tuber cinereum/mammillary bodies (corresponding to the rostral and caudal walls of an expanded lower (hypothalamic portion) of the 3rd vent) distention of the optic and infundibular recesses, and abnormal rotation of the ventrally displaced optic chiasm/visual pathway. Yes No There may be additional (secondary) imaging features of elevated CSF pressure including optic hydrops, hyperdynamic CSF pulsations, cerebellar tonsillar sagging, and ventricular diverticula. Yes No Given there is obstructive 4th ventricular enlargement (sequestered vent or obstructing mass), there is now upward incisural herniation. Yes No There is evidence of epencymal cicatrix with sequestered ventricle under pressure. Yes No There is evidence of grade 1-4 ex vacuo ventriculomegaly without progressive hydrocephalus. Yes No There is evidence of subarachnoid or intraventricular acute or subacute blood products with some degree of hydrocephalus. Yes No There is evidence of arrested or normal pressure hydrocephalus: has stable ventriculomegaly with at least some features of elevated CSF pressure. Yes No There is unexplained downward incisusal and tonsillar herniation, with or without ventriculomegaly, which is most consistent with intracranial hypotension (ICH). Yes No Other significant imaging findings are present. Yes No
