Inflammatory lesions and tumors of the nasal cavities and paranasal sinuses with skull base involvement.
The size and location of these masses can be accurately assessed today with appropriate imaging studies. The radiologist, however, must pay attention to detail and carefully evaluate the margins of the lesion and note its precise size because this information determines the operation and operative approach used. In addition, by carefully analyzing the imaging characteristics, a fairly accurate preoperative diagnosis can be given that will allow treatment planning to precede until final pathologic confirmation is available.
