MR imaging of presumed olivary hypertrophy in palatal myoclonus.

Abstract

Rhythmic palatal myoclonus is a neurologic sign with one of the most precise patnologic correlations. It almost always is associated with hypertrophic degeneration of the inferior olivary nucleus. We present a case that we think illustrates the MR detection of hypertrophic degeneration of the inferior olivary nucleus (2)
