Fig 4. T2 short-
inversion recovery (STIR) MR coronal image obtained from a 74-year-old male normal control (NC) patient. A, Arrowhead shows a small hippocampal sulcus residual cavity (HSC); arrow shows perihippocampal fissures (PHF) (uncal sulcus). B, 3-year follow-up scan. Comparing A and B, there is progressive dilation of the uncal sulcus (arrow), but no obvious change in the size of the HSC (arrowhead).
