The ventricles, sulci, and cisterns are age appropriate in size and configuration. There is no evidence for restricted diffusion. There is mucosal thickening lining the walls of the left maxillary sinus, also containing an air fluid level with two different levels within it, most likely from proteinaceous differences.
