14-yr-old with extensive med hx, including sagittal craniosynostosis and Nevoid Basal Cell Carcinoma Syndrome which has produced multiple lower mandible tumors, has recent MRI findings of bilateral ethmoid and maxillary sinus mucosal thickening, (most pronounced on right side), and trace bilateral mastoid air cell fluid signal noted. What does this mean and could it have anything to do with med hx noted above?
