Background
Hypertrophic olivary degeneration is a transynaptic degeneration that occurs as a result of a lesion which damages the neuronal fibers of the dentate-rubro-olivary (DRO) pathway. The DRO pathway is formed by the red nucleus, the ipsilateral inferior olivary nucleus, the contralateral dentate nucleus and the neuronal fibers connecting these nuclei. A triangular relationship between these three structures was originally described by French physicians Georges Guillain and Pierre Mollaret in 1931 and is therefore also known as the triangle of Guillain and Mollaret [1].
