Three months after brainstem hemorrhage, MRI revealed a hyperintense lesion of the left inferior olivary nucleus of a 45-year-old man (figure). The patient was completely asymptomatic, but exhibited oculopalatal tremor (OPT), rhythmic palatal oscillations, and small-amplitude vertical pendular nystagmus of the right eye, best visualized on fundus examination (see video).

Figure MRI, axial T2 sequences

Initially: right inferior colliculus hemorrhage (A, arrow) and normal inferior olivary nucleus (B). Three months later: resolution of hemorrhage (C, arrow) and left inferior olivary nucleus hyperintense signal (D, arrow).

OPT is caused by interruption of the inhibitory dentato-olivary pathway, resulting in synchronous oscillations of the olivary neurons. This pathway crosses the midbrain then descends to the contralateral inferior olivary nucleus.1,2

Asymptomatic OPT is rare. Micronystagmus can be overlooked with simple observation but is readily detected during fundus examination.
