My friend, I am no radiologist, but my first thought is also that your head may have been tipped a bit to one side, so when they take the “slice” through the head, it could appear asymmetrical. I would think, if that was the case, as the slices kept going higher both ventricles show up? Is that what you see? Perhaps a radiologist or other medical person could chime in? #PatientsHelpingPatients 😉
