Laterotrusion (Side to Side) and Protrusion/Retraction Difficulty of Tongue in Two Children with Wilson's Disease

Involvement of tongue is uncommon in Wilson's disease (WD) in early stages. This is usually seen late when the patient has an established neurological WD associated with dyskinesia, dystonia, and tremors. In this article, we presented two children with tongue involvement in which there were slow laterotrusion (side to side) and protrusion and retraction movements. In the first child this was the early and only manifestation without any other neurological features while in the second child this was seen in a previously diagnosed WD. Slow tongue movements in any child with or without extrapyramidal features should be investigated to rule out a treatable condition like WD. Tongue involvement is common in children with different neurological/neuromuscular diseases, drugs, and other unknown conditions.
