A girl with bilateral temporomandibular joint pain, generalized arthralgias, and inability to walk.

ABSTRACT

The authors present the case of a 6.5-year-old girl with bilateral temporomandibular joint (TMJ) pain, generalized arthralgias, inability to walk, and absence of deep tendon reflexes in the context of Guillain-Barrè syndrome. TMJ pain was the sole manifestation for 3 days, before other typical symptoms appeared, an issue that initially led to an improper diagnosis. A thorough clinical examination along with laboratory and radiographic evaluation excluded other possible causes of TMJ pain. To the best of the authors' knowledge, this is the first case of Guillain-Barrè syndrome in the pediatric population initially presenting with bilateral TMJ pain. Guillain-Barrè syndrome may be quite atypical in its expression, especially in young children, with pain being a common presenting symptom, and pediatricians should be alert to avoid misdiagnosis.
