Neuroimaging features in a case of developmental central auditory processing disorder

We describe a case of developmental central auditory processing disorder (CAPD) that was diagnosed with a multidisciplinary approach including structural and functional neuroimaging. A patient with developmental CAPD was investigated using diagnostic tools of MRI and 18F-FDG HRRT-PET as well as neuropsychology and electrophysiology. Besides impaired auditory processing, our patient also showed some impediments in supramodal, cognitive and linguistic processes. His MRI showed selective atrophy in the bilateral auditory cortices, and the PET images showed hypometabolism in the bilateral auditory cortices and the precuneus. Such a multidisciplinary diagnostic approach that includes neuroimaging methods will be helpful in differentiating developmental CAPD from other developmental cognitive disorders.
