title: Malignant tumors of the paranasal sinuses: radiologic, clinical, and histopathologic evaluation of 200 cases.
abstract: Malignant tumors of the paranasal sinuses are often found to be greatly advanced by the time a clinical or radiologic diagnosis is established. Therefore, the overall cure rate is low, even when surgery and radiation therapy are combined. The clinical manifestations and pathologic findings are analyzed in 200 cases to illustrate the wide spectrum of these tumors as to their type, specific location, and the extent to which they can spread within the sinuses and to adjacent anatomic areas. The various radiologic modalities, including conventional x-ray films, angiography, and conventional and computed tomography are presented. Their relative merit in the diagnosis and staging of these tumors is evaluated.
