Objective To investigate the CT features of nasal malignant lymphoma. Methods Retrospective analysis of 11 cases of pathologically confirmed nasal malignant lymphoma CT and clinical data. The results of the main CT manifestations: ① from the side of the nasal vestibule or nasal front, a wide range; involving single or bilateral nasal cavity. ② a slight limitation of bone destruction, mainly occurs in the lower part of the nasal septum, the upper wall of the maxillary sinus and the inferior turbinate and other places. ③ lesion ipsilateral paranasal sinus at the same time easily involved in the maxillary sinus most obvious, manifested as uniform soft tissue or along the wall growth and the central residual air cavity. ④ easy to spread to the adjacent structures, including the contralateral nasal cavity, nose, face, parapharyngeal and maxillary sinus fat gap and so on.
