Herniation of the cerebellar tonsils
(occipital cone) is a complication of
expansive processes in the posterior
cranial fossa. The herniated cer-
ebellar tonsils lead to compression
of the medulla oblongata inside the
foramen magnum. The most com-
mon clinical signs are headache
located in the occipital region, dip-
lopia (double vision), impairment of
muscle control (weakness or palsy),
and ataxia. Rapid progression typi-
cally leads to impairment of con-
sciousness and failure of the cardio-
vascular system and breathing.
