Significant dilatation of all cerebral ventricles, transverse diameter of the third ventricle is 17 mm. Periventricular edema: band-like diffuse signal increase on T2-weighted and FLAIR images along the walls of lateral ventricles. Accented CSF flow signal void in aqueduct on T2-weighted axial images with dilatation of cerebral aqueduct. Lack of ventricular obstruction. Disproportional widening of basal and Sylvian CSF fissures and ventricles and narrowing of medial parasagittal fissures. Lack of deformation of the 3rd ventricle's floor, indicating normal interventricular pressure, pointing at "normal pressure hydrocephalus". Callosal angle is 74 degrees, Evan's index is 0,36. No abnormal contrast enhancement, excluding meningeal and/or arachnoidal lesions, which may cause a resorbtive hydrocephalus.
Incidental development venous anomaly with cavernous hemangioma in the right hemisphere of the cerebellum.
