The aim of the present study was to determine morphological variations
in the lobules IV-V of the human cerebellar hemispheres.
Material and methods. The research involved cerebella of 100 people of
both sexes, who died of causes unrelated to brain pathology at the age of
20-95. The parasagittal sections of the cerebellum were investigated.
Possible variations in the size, shape and peculiarities of branching of the
white matter in the lobules IV-V of the cerebellar hemispheres were
investigated.
Results. Complex branched white matter is the basis of the IV-V lobules
of human cerebellar hemispheres. The shape of the IV-V lobules is quite
varied. Differences of the structure of these lobules depend on the
characteristics of the branching of the white matter. The shape of the
lobule depends on location of the section. Structure of the lobules is
different on serial parasagittal sections. We described 2 variants of
branching of the white matter of the hemispheric lobules IV-V at a
distance 5 mm from midsagittal section (the 2nd variant is the most
common) and 10 common variants of the shape of IV-V lobules (10 mm
from midsagittal section); the third variant is the most common variant of
the lobule IV; the first, second, and third variants are the most common
shape variants of the lobule V.
Conclusion. Described variants of the shape of the cerebellar lobules can
be used as criteria standards of modern diagnostic imaging techniques
for the diagnosis of various diseases of the CNS.
