A 1 mm slice thickness axial 3D T1-weighted image shows continuity from the herniated tissue (arrow) to the uncus and parahippocampal gyrus, with clear separation of white and gray matter.

An additional three-dimensional (3D) T1 sequence (BRAVO) with 1 mm slice thickness on a 1.5 T machine (GE Healthcare, Milwaukee, WI, USA) was performed, which very clearly illustrated full continuity from the tissue to the uncus and parahippocampal gyrus, and with clear separation of white and gray matter (Fig. 1).
A coronal T2-weighted image, which shows nicely how, mesial temporal parenchyma (arrow) crawling on the edge of the tentorium and settles subtentorial in ambient cistern.

Images nicely depicted how mesial temporal parenchyma crawl on the edge of the tentorium and settles subtentorially in ambient cistern (Fig. 2).
An axial CT scan of the cerebrum, performed 4 years earlier, on which one could recognize the MRI verified herniation of left parahippocampal gyrus (arrow).

During the previous hospitalization 4 years earlier a computed tomography (CT) scan of the cerebrum was carried out, in which one barely recognize herniation of the parahippocampal gyrus (Fig. 3).
