Cranial nerve involvement in Charcot –Marie–Tooth Disease

Discussion CMT is a group of disorders with a wide range of clinical presentations and abnormalities. Cranial nerve involvement is infrequently described in CMT 1A. In our case and prior studies, there does not appear to be a correlation between cranial nerve involvement and symptoms. Trigeminal neuralgia has been described in patients in CMT, but is not common and was not seen in our patient despite abnormal trigeminal nerve findings on imaging. Our patient also demonstrated involvement of the facial nerve without facial muscle weakness. Clinical features are key in distinguishing CMT 1A from other forms of HMSN.
