Title: Squamous cell carcinoma of the sinonasal cavities. Author: Hermans R, De Vuysere S, Marchal G. Journal: Semin Ultrasound CT MR; 1999 Jun; 20(3):150-61. PubMed ID: 10378249. Abstract: Squamous cell carcinoma of the sinonasal cavity is an uncommon neoplasm. The symptoms of this tumor are aspecific, and the diagnosis is often made in an advanced stage of disease. Imaging is necessary for evaluating paranasal extension and possible intracranial spread, orbital involvement, infratemporal extension, spread to the nasopharynx, oropharynx, or oral cavity, and spread along neurovascular bundles or perineural spread. Sinonasal cancers are studied with CT or MRI, and in many cases both modalities are used, as they often offer complementary information. The CT and MRI appearance of this kind of tumor is reviewed in this article.[Abstract] [Full Text] [Related] [New Search]
