HIPPOCAMPAL SCLEROSIS

Q.All are true regarding hippocampal sclerosis except
a. The amygdala remains superior to temporal horn
b.  the CSF signal in the uncal recess of temporal horn / the alveus seprate amygdale from hippocampus
c. Both amygdala and hippocampus are hypointense to gray matter on almost all  MR pulse sequences.
d.The hippocampus may be slightly hyperintense to gray matter on FLAIR images

e. the posterior hippocampal boundary for volumetry extend to the crus of the fornix  


ANS.----c
Both amygdala and hippocampus are isointense to gray matter on all MR pulse sequences. The hippocampus, however, may be slightly hyperintense to gray matter on fluid attenuated inversion recovery (FLAIR) images due to incomplete suppression of CSF
