Abstract

Hypertrophic Olivary Degeneration is rare transsynaptic degeneration secondary to lesions involving the anatomical triangle of Guillain and Mollaret or the dento-rubro-olivary pathway. Here we present a case of 37 year male with history of pontine bleed 6 months back with residual left spastic hemiparesis, able to walk without support after 2 months of initial stroke. Now presented with 6 weeks history of severe ataxia of gait and in coordination of limbs with action and intention tremors of extremities. MRI Brain showed presence of bilateral Hypertrophic olivary degeneration. Thus in patients with brainstem strokes with improvement initially followed bydelayed worsening with fresh cerebellar signs and tremors, a possibility of hypertrophic olivary degeneration should be considered. This may help us avoid unnecessary investigations and evaluation.
