| Résumé : | A paradoxical vestibular syndrome caused by a fibroblastic meningioma is described in a 20 month-old Holstein heifer. Clinical signs included head tilt, jerking movements of the head and neck, circling to the left, and also abducted and hypermetric right limbs. The animal was culled and the forebrain therefore was unavailable for histopathological study. The tumour was found on the right side, adherent to the dura mater at the level of the ponto-medullary junction. The paradoxical vestibular signs were explained by the presence of the mass causing a loss of cerebellar inhibition over homolateral vestibular nuclei resulting in hyperactivity on the same side as the tumour and simulating a contralateral functional loss. The jerking head and neck movements might be caused by the same lesion although a concurrent forebrain lesion could not be excluded. |
