The Silent Triangle Speaks: Hypertrophic Olivary Degeneration Unveiled
Abstract: Background: Hypertrophic olivary degeneration is an uncommon form of trans synaptic degeneration affecting inferior olivary nucleus. It mostly develops secondary to a destructive lesion involving the Guillain?Mollaret pathway. It presents with symptomatic palatal tremor, less frequently can cause dentatorubral tremor (Holmes tremor). In some cases, these tremors may also involve facial muscles, diaphragm, or muscles of the tongue and larynx.HOD commonly develops secondary to a focal lesion like haemorrhage, infarction, tumours, infection, inflammatory conditions, trauma, or post-surgical. In rare cases, HOD has been documented to be idiopathic. Case presentation: We present a case of a 29-year-old male with complaints of diplopia, syncopal attacks. On physical examination, ocular tremors was seen. Patient had no significant past medical history. There was no history of trauma, neurosurgical interventions.
