RESUMO
Objective:Analysis of nasal lymphoma CT and MRI data, summarize imaging characteristics, provide help for clinical diagnosis. Method:Retrospectively analyzed the image manifestations of 32 cases of nasal lymphoma diagnosed by surgery and pathology. Lesion locations, tumor extension, bone destruction and its density, signal characteristics, enhancement degree, the situation of adjacent tissues were evaluated. Result:NK/T cells, T cell NHL have the characteristics: the lesions to diffuse growth, widely existed in nasal breathing zone, often involving middle and inferior turbinate, local bone slightly damaged, and no obvious bony shift. Tumor of uneven density, fuzzy boundaries, mixed signalse. The characteristics of B cell NHL: the lesion originated in the front of the nasal cavity, on the surrounding adjacent tissue compression performance, local feature is swelling growth and bone have insect damage sample sample, the dotted line change, very mild osseous shift, the tumor boundary is relatively clear, lesions density is uniform, and part of the uniform tumors had signal. Conclusion:Nasal lymphoma imaging changes have its characteristics. Image change prompts the pathological classification, providing help for clinical diagnosis.
