Could Ventricular Dilation And Cingulate Sulcus Changes, Be Related To A Recent Concussion, Or Might They Indicate Normal Pressure Hydrocephalus?

This is from my MRI report what does it mean? NTERPRETATION: There is prominent dilatation of lateral ventricles and to a lesser extent the third ventricle. There is upward bowing of the corpus callosum. There is a cingulate sulcus sign with the posterior half of cingulate sulcus being narrower than the anterior half. There is a callosal angle is 68 degrees. The Evans index is .45. The left temporal horn measures 8 mm in width. These findings may be seen in cases of normal pressure hydrocephalus. No intracranial mass lesion, hemorrhage, or territorial infarction is demonstrated. Diffusion-weighted images show no regions of restricted diffusion. There are a few small foci of hyperintensity on long TR images in the periventricular and deep white matter suggestive of mild microvascular ischemic changes. Visualized portions of the sinuses and mastoid air cells are clear. I recently suffered a concussion is this related to that?
