Bilateral involvement in hypertrophic olivary degeneration [Bilateral hipertrofik olivar dejenerasyon]

Hypertrophic olivary degeneration (hod) is a form of trans-synaptic degeneration with hypertrophy of the inferior olivary nucleus in response to neurologic insult to the dentatorubro-olivary pathway. in the central nervous system,the degeneration of an anatomical structure is usually characterized by neuronal loss replaced by proliferation of glial elements. unique to the inferior olivary nucleus is transneuronal degeneration resulting in hypertrophy of the targeted region. hod is a relatively rare disorder that may mimic many diseases including tumors and demyelinating processes. herein we report on a case of hod with bilateral involvement and we present the follow-up findings.
