title: Computed tomography of sinonasal non-Hodgkin lymphoma.
abstract: Seven cases of primary malignant lymphoma of the nasal cavity and paranasal sinuses were examined with computed tomography. Histology was "diffuse non-Hodgkin lymphoma" in all cases. Computed tomography clearly delineated the extent of the tumors, which involved either the maxillary sinus or the nasal cavity and extended into the subcutaneous tissue of the cheek, as well as in the infratemporal fossa or nasopharynx. Bony wall destruction was evident in only three cases; it was slight and clearly less marked than the destruction usually encountered in cases of carcinoma.
