Inferior pontine segmentation abnormality in a child with sensorineural deafness: DTI analysis of fiber tracts.

MRI/DTI data are presented in a child with sensoneurinal hearing loss and swallowing disorder. MRI/DTI revealed hypoplastic 8th cranial nerves and an inferior pontine segmentation abnormality. Color-coded FA-maps revealed diminished/absent fiber tracts within the affected brainstem segment. This report may add another small puzzle piece to the ongoing research on brainstem malformations.
