【Abstract】 Objective To evaluate the diagnostic value of CT and MRI in the NK/T cell lymphoma in nasal
and paranasal sinus. Methods CT and MRI images of twenty patients with surgically confirmed NK/T cell lymphoma,
who were enrolled in this study from July 2010 and April 2015, were retrospectively reviewed and analyzed with focus-
ing on the lesion location, invasive range, CT density, MRI signal features, calcification degree and involvement of sur-
rounding parenchyma and lymphonoduli. Results All 20 lesions showed iso-density on CT images with no obvious cal-
cification (CT value range: 42~69 Hu). Of these, 8 cases of bone destruction without calcification tumor were observed.
Among 16 cases undergoing MRI examinations, all the lesions showed homogeneous (n=13) or heterogeneous (n=3)
isointensity on T1WI, and hypointensity signal (n=12) or isointensity signal (n=4) on T2WI, with homogeneous (n=10)
or heterogeneous (n=6) signal intensity. Moderate enhancement occurred in 12 patients and mild enhancement in 4 pa-
tients. Conclusion CT and MRI can accurately demonstrate the lesion location and invasive range of lymphoma in na-
sal and paranasal sinus, and some imaging features can be helpful for preoperative diagnosis.
