[CT examination and diagnosis of oral and maxillofacial tumors invading the pterygopalatine space].
CT findings in 33 cases (proven histopathologically) suffered from oral and maxillofacial tumors affecting the pterygopalatine space were retrospectively analyzed. The authors conclude that the main CT manifestations of this space involvement by tumors can be depicted as a soft tissue mass occupancy and the wall structures destruction. Tumors occurring in different locations of oral and maxillofacial areas have different features of CT appearances. In addition, the primary tumor of this space is probed from histogenesis and CT findings, and its diagnostic criteria are discussed. As a modality of imaging, CT has an important role for assessing the lesions of this fossa.
