Ageusia associated with thalamic plaque in multiple sclerosis.
Ageusia and the cheirooral syndrome developed in a patient with a relapse of multiple sclerosis. Magnetic resonance imaging revealed an area of demyelination in the thalamus. This lesion presumably affected the most medial part of the ventralis posterior nucleus, where taste information is located. Given the proximity of the taste area and somatosensory representation of the hand and oral cavity in the ventralis posterior nucleus, we propose that a diagnosis of thalamic lesion should be considered when ageusia occurs with the cheirooral syndrome.
