Figure Facial features and brain MRI
(A) Facial features of patient at age 1, 3, 7, and 43 years, with attention to the
diagnostic clue, her enlarged and calcified external ear. Important early features
include prognathism, repaired cleft palate, anteverted nares, prominent ears, and
nasal roots. Early prognathism gave way to micrognathia in subsequent years. Ptosis
was not apparent in early childhood. (B) Sagittal T2-weighted brain MRI demonstrates
partial agenesis of the corpus callosum with “wandering” of the
anterior cerebral arteries and high-riding third ventricle. (C–E) Increased
fluid-attenuated inversion recovery signal is seen in patchy subcortical and diffuse
periventricular distribution. (E–G) Coronal T2-weighted sequences demonstrate
partial calcification of the putamen and globus pallidum and teardrop deformity of
the lateral ventricles. The brainstem and cerebellum showed normal size and
configuration. The patient's mother has given full informed consent for the
publication of the video and images.
