Morphometric Analysis of Hemicerebellar Asymmetry with Central Vertigo Cases: A Stereological Study

Abstract

We aimed to evaluate the relevant methods of stereology to estimate hemicerebellar asymmetry according to sex in both adult right handed vertigo cases and comparing with healthy cases. The study included 14 adult control subjects and 18 patients with vertigo. The volumes of the cerebellar hemispheres were determined by MRI using the point-counting approach of stereological methods. The mean (+/- SD) of the right cerebellar hemispheres in the patients with vertigo were 52.49 +/- 5.42 cm(3) in males, 50.11 +/- 4.02 cm(3) in females. The mean ( SD) of the left cerebellar hemispheres in the patients with vertigo were 53.11 +/- 3.70 cm(3) in males, 49.73 +/- 4.69 cm(3) in females. There was not significant quantitative evidence detected in terms of cerebella asymmetry between sagittal plane estimates in the cases with vertigo in both genders (p>0.05). There were no statistically significant differences according to the genders between both vertigo and control subjects (p>0.05). There was only statistical significance between right and left hemispheres in male control subjects (p=0.039). There was no cerebella asymmetry between control and vertigo cases according to genders. The stereological evaluation of cerebella asymmetry or atrophy in humans correlate with gender is of importance for both clinicians and anatomists. The technique is simple, reliable, inexpensive and unbiased.
