Hypertrophic olivary degeneration

Discussion:

Hypertrophic olivary degeneration is a rare condition characterized by unique pattern of trans-synaptic degeneration. It is caused by a lesion in the triangle of Guillain and Mollaret, resulting in hypertrophy of the inferior olivary nucleus. In this case the previous hemorrhagic lesion in the right dentate nucleus caused the interruption that led to hypertrophic olivary degeneration.
