Objective: To explore the CT characters of non-Hodgkin's lymphoma initially located in nasal cavity and paranasal sinuses.
Method: The CT manifestations of 9 non-Hodgkin's lymphoma initially located in nasal cavity and paranasal sinuses verified by pathology were analysed retrospectively.
Result: 1) Non-Hodgkin's Lymphoma of nasal cavity and paranasal sinuses is essentially malignant, acts as a typical malignancy in its clinical manifestation, but on CT, its bone destruction acts as a benign tumor consisting of bone remodeling. 2) Hypertrophic mucosa lies on septum chiefly. 3) Mass with soft tissue density always involves in inferior meatus and inferior turbinate.
Conclusion: The CT manifestation of non-Hodgkin's lymphoma initially located in nasal cavity and paranasal sinuses has its own characters.
