1 A 16-year-old boy with rhabdomyosarcoma.
A 16-year-old boy with rhabdomyosarcoma. A, Bone window from a noncontrast CT examination show opacification of the right-sided paranasal sinuses, including the right sphenoid sinus (arrow). There are areas of dehiscent bone involving the maxillary sinus walls. B, Soft-tissue window shows the lesion involving the right nasal cavity, right maxillary and sphenoid sinuses, right orbit, and right pterygopalatine fossa (white arrow). Note the normal fat within the left pterygopalatine fossa (black arrow). Y.W. Lui et al. AJNR Am J Neuroradiol 2011;32: ©2011 by American Society of Neuroradiology
