Dear Editor,

Hypertrophic olivary degeneration (HOD), a rare condition, is characterized by a unique pattern of trans-synaptic degeneration caused by injury to the brainstem or cerebellum within the triangle of Guillain and Mollaret [1]. Bilateral Wallerian degeneration (WD) of the middle cerebellar peduncles is caused by interruption of crossed cortico-ponto-cerebellar pathways and is rarely reported in the literature [2]. The three most common types of main transaxonal degeneration involving cerebellar connections are hypertrophic olivary degeneration, Wallerian degeneration of the middle cerebellar peduncle, and crossed cerebellar diaschisis (CCD). The occurrence of any one of these phenomena is very rare, and they are therefore usually reported separately in the literature. Here, we report a patient who presented with the neuroradiological findings of WD involving the bilateral middle cerebellar peduncles secondary to brainstem hemorrhage, as well as abnormal signaling in the...
