The findings at CT in 11 patients with primary non-Hodgkin lymphoma (NHL) of the maxillary sinus were compared with the CT findings in 21 patients with squamous cell carcinoma (SCC) of the maxillary sinus. In NHL, the segmental bone destruction was in alignment with the bony wall with a massive tumor infiltration into the neighboring structures. In contrast, all patients with SCC were characterized by a soft tissue mass with aggressive bone destruction. About half of the patients with NHL had cervical lymphadenopathy. Post-treatment recalcification of previous bone destruction was seen in 4 out of 5 NHL patients on follow-up CT. In the patients with SCC, only a few had metastatic lymphadenopathy, and no recalcification occurred after treatment. CT is therefore of importance in differentiating NHL from SCC of the maxillary sinus.
将11例上颌窦原发性非霍奇金淋巴瘤（NHL）患者的CT表现与21例上颌窦鳞状细胞癌（SCC）患者的CT表现进行了比较。在NHL中，节段性骨质破坏与骨壁一致，有大量肿瘤浸润至邻近结构。相比之下，所有SCC患者均表现为伴有侵袭性骨质破坏的软组织肿块。约半数NHL患者有颈部淋巴结肿大。5例NHL患者在随访CT上可见先前骨质破坏的治疗后重新钙化。在SCC患者中，只有少数有转移性淋巴结肿大，治疗后未发生重新钙化。因此，CT对于鉴别上颌窦NHL和SCC具有重要意义。
