Bilateral Wallerian Degeneration of the Middle Cerebellar Peduncle and Unilateral Hypertrophic Olivary Degeneration Secondary to Pontine Hemorrhage: A Case Report

ABSTRACT

The two distinct types of axonal degeneration that occur after neuronal injury include Wallerian degeneration (WD) and transneuronal degeneration. The most commonly recognizable cause of secondary degeneration is cerebral infarction, but may also include a variety of conditions including hemorrhage, trauma, necrosis, and focal demyelination. Herein, we present a rare case of WD of the cerebellar peduncles accompanied by unilateral hypertrophic olivary degeneration following pontine hemorrhage.
