Background. Topography of the human corpus callosum has occasionally studied in different populations. Aim. The purpose of this study was to evaluation the morphology of human corpus callosum in Iranian population via magnetic resonance imaging. Material and Methods. Retrospective cross-sectional study. Design of the study was retrospective cross-sectional study. Seven hundred and seven normal magnetic resonance imaging (MRI) were enrolled to our study. The shape, anterior-posterior length and area of corpus callosum as well as their relationship with gender, age, and handedness were assessed. Results and Discussion. The most common and uncommon form of corpus callosum were splenial bulbosity form (35.6%) and arch mid-body form (7.2%) respectively. Maximum anterior - posterior (AP) distance of corpus callosum was longer in male and older age individuals compared to female and younger ones respectively. No significant differences were seen in AP distance of corpus callosum between right and left handers. Area of corpus callosum was widened in male and younger age individuals compared to female and older ones respectively. Conclusions. The findings of this study show morphology of corpus callosum in Iranian population. Morphometric parameters of AP and area of corpus callosum are related to sex and age but no to handedness.
