Möbius syndrome


In this case, the referring Ophthalmologist already had a working diagnosis of Möbius syndrome prior to imaging. The combination of facial nerve palsy and abducens nerve palsy is characteristic, and high resolution T2 imaging should be obtained in these cases to examine the cisternal portions of the facial nerve. Although, the abducens nerve is not routinely visualized on imaging, the absence of the facial colliculi should be sought, as they are mainly formed by the abducens nerve nuclei.
