Bilateral mesial temporal sclerosis


10-15% of MTS is bilateral, if comparison and primary findings of atrophy are used alone the diagnosis may be missed

Secondary findings will help diagnose more cases. They are:

  • mamillary body atrophy, 
  • temporal horn dilation, 
  • reduced digitations, 
  • reduced parahippocampal grey-white matter differentiation and 
  • decreased thickness of collateral white matter

Secondary findings also help to decide the side to be operated for maximal patient benefit.

if all MRI findings and EEG are equivocal, FDG-PET is used.
