INTENTION TREMOR AND OLIVARY ENLARGEMENT - CLINICORADIOLOGICAL STUDY

This study describes two patients who presented with intention tremor (IT) concomitant with olivary enlargement (OE), and discusses the rela tionship between these phenomena, Both patients had a vascular lesion in the brain stem, which subsequently caused IT and OE ipsilateral or contralateral to the site of the lesion, depending on the structures e ffected by the lesion, The results of our study suggest that damage in volving the superior cerebellar tract, and central tegmental tract, or both, may result in IT and OE, However, IT and OE appear to have litt le physiological association, unlike the relation between OE and palat al myoclonus.
