Fourth ventricle normal in size and position. No shift midline structures. There are a couple of tiny white dots adjacent to the anterior commissure on each side, more prominent on the right that probably represent perivascular spaces. There is another white dot in the posterior aspect of the right centrum semiovale as well as several on the left superiorly. These most likely represent prominent perivascular spaces as well.
Nothing radiates toward the corpus coliseum.
