There are no acute intracranial abnormalities. The calcarine sulcus is quite deep bilaterally, resulting in prominent lateral protrusion of the medial walls of the bilateral occipital horns.
Case Discussion
Deep calcarine sulci and prominent calcar avium, a normal variant. On axial views, one may mistake the lateral aspects of the calcarine sulci as hemorrhage in the occipital horns. This is also a potential mimicker of grey matter heterotopia and schizencephaly.
