Radiological features are depicted in this study. (A) Evaluation of hydrocephalus entailed the use of CT scans and Evans’ index, which measures the ratio between the maximum width of frontal horns (a) and the maximal internal diameter of the skull (b) at Monro’s foramens. (B) Temporal horn widths are measured strictly at the ventricular prominence level. (C) Third ventricle width, (D) Ventricular width refers to the narrowest distance between walls on both sides of the lateral ventricle body, measured axially; CT slices should be taken where the cella media first appears unobscured by other regions (thalamus) (G) subdural hygroma after surgery (arrow). (E,F) Corpus callosal angles are measured on coronal planes perpendicular to each subject’s anteroposterior commissure plane on their posterior commissure. (H,I) CT values around anterior horns intervals a patient 7 days after admission (circles place).
