The comparative analysis of volume indicators of the posterior cranial fossa lesions in groups of patients with the cerebellar tonsils dislocation caused by tumors and occipital hypoplasia was performed. Similar values of «volume deficit» of the posterior cranial fossa were identified both by absolute (20 and 30 ml) and relative (0.13 ml/cm of height) indicators. Comparability of these indicators may prove the existence of common stages in the pathogenesis of the cerebellar tonsils dislocation of different etiologies.

Key words: axial cerebellar dislocation, posterior cranial fossa, subtentorial tumors, Chiari malformation.
