Zusammenfassung:•A comatose 70-year-old female patient with hemispheric cerebral hemorrhage without brainstem involvement was brought to the hospital.•The patient presented with a unilateral loss of oculocephalic reflex on head rotation without conjugate eye deviation.•This finding suggests that the input pathway from the vestibular nuclei to the paramedian pontine reticular formation (PPRF) is not independent from that from the frontal lobe.
