Hypertrophic Olivary degeneration (HOD) is a rare type of neuronal degeneration involving the dentatorubro-olivary pathway. It is a secondary change caused by the impairment of Guillain Mollaret triangle. We present a case of a thirty-five years old man who had head injury with MR evidence of haemorrhagic contusion at the ponto-mesencephalic junction extending into the superior cerebellar peduncle on left side. Five months after the injury he developed left upper extremity rhythmic tremor. Repeat MRI permitted visualization of hypertrophic olivary degeneration, which appeared as a characteristic high signal intensity in the right inferior olivary nucleus on T2 W and FLAIR images, with enlargement of the nucleus. The literature and imaging findings of this uncommon condition are reviewed.
