1. Unremarkable noncontrast MRI of the head. Of note, the postcontrast portion of the examination was inadvertently not performed. If post contrast images remain clinically warranted as leptomeningeal enhancement cannot be excluded on this exam, postcontrast imaging can be rescheduled.2. Maxillary sinus mucosal thickening. Please correlate clinically.
