The diagnosis of Moebius syndrome, a rare congenital disorder, is primarily 
based on congenital facial and abducent nerve palsy. Involvement of other 
cranial nerves is also common. Occasionally the V, X, XI, and XII cranial nerves 
are involved, resulting in a difficulty to chew, swallow, and cough, which often 
leads to respiratory complications. Mental retardation and autism have been 
reported in some cases. Moebius syndrome can be associated with orofacial 
anomalies and limb malformations. The authors describe a patient with a 
confirmed diagnosis of Moebius syndrome associated with hydrosyringomyelia. No 
case of Moebius syndrome involving primarily the spinal cord has been reported 
so far. This patient did not present with other factors directly linked to 
syringomyelia.
