Popis: A 21-year-old right-handed man developed progressive dysarthria and gait disturbance over 4 months (associated with intermittent hiccups). During that time, he also suffered from uveitis. A physical examination showed pseudobulbar and pyramidal signs and genital and oral ulcers. A brain MRI revealed an extensive lesion mainly located in the ventral pons, with an extension upwards to the midbrain. The inferior olivary nucleus also showed hyperintensity. After the treatment with intravenous methylprednisolone and pulses of cyclophosphamide, he improved. As observed on his MRI, his lesions also improved, except for an increase of the inferior olivary nucleus, consistent with hypertrophic olivary degeneration. Neuro-Behçet tropism for ventral brainstem explains the usual presentation with pyramidal syndrome. Hypertrophic olivary degeneration due to pons involvement could explain the hiccup attacks in a few known cases.
