Otorhinolaryngological imaging findings. MDCT temporal bone exam in a 12-year-old female with MPS VI. Axial scans presented from caudal to cranial (a-b-c) demonstrate nasopharyngeal airway and Eustachian tube narrowing (arrow); thickened tympanic membrane (arrowhead); opacification of mastoid cells and left middle air cavity (curved arrow). Other abnormalities, including mucosal thickening of ethmoidal air cells, poor pneumatization of sphenoidal bone and maxillar sinus cavities and impacted teeth, are also depicted. Coronal view of temporomandibular joints (d) shows flattened and deformed mandibular condyles (empty arrow)
