Materials   and   Methods:   The   study   was   done   from   Feb   2009   to   July   2010.   Materials   for   the   study   were   collected   from   K.R.Hospital   attached   to   M.M.C   &   R.I. Mysore.    200    normal    CT    scans    of    patients    were    collected    (100    male    and    100    females).    Measurements    were    taken    as    follows,    1)    at    the    level    of interventricular   foramen   (IVF)   -   IVF   to   tip   of   frontal   horn,   2)   from      IVF   –   from   IVF   to   collateral   trigone   and   Posterior   horn   from   collateral   trigone   to   tip   of posterior   horn,3)      below   the   level   of   IVF   -   Transverse   diameter   and   Height   of   inferior   horn.   Results:   All   the   measurements   except   inferior   horn   were   more   in males   compared   to   females   and   more   on   left   side   than   right   side.   Measurements   of   inferior   horn   transverse   diameter   (TD)   the   right   side   were   slightly   (0.2 mm) more than left side in males and equal in females. Height (HT) of inferior horn was 0.3 mm more on right side in males and 0.1 mm in females. Conclusion:   The   study   shows   the   normal   range   of   measurements   of   different   parts   of   lateral   ventricles   in   male   and   female   patients.   Left   ventricles   are larger than right side in males compared to females.
