The radiographic manifestation of malignant lesions of the maxillary sinus on dental radiographs may be nonspecific, making it difficult to differentiate the lesion from disease of odontogenic origin or more benign sinus pathoses. A radiopaque mass in the maxillary sinus, resulting from a malignant neoplasm growing within or extending into the sinus, can be easily confused with the mass of a mucous retention pseudocyst. Similarly, a malignant growth in the early stages of development can produce radiographic patterns in the alveolar process that may resemble inflammation of odontogenic origin. A case of B-cell lymphoma is reported. The lesion involved the maxillary alveolar process and sinus, producing such a radiographic pattern on the panoramic radiograph. Radiographic and clinical features that should be considered in establishing a differential diagnosis of malignant disease are discussed.
上颌窦恶性病变在牙科X线片上的影像学表现可能不具有特异性，这使得难以将该病变与牙源性疾病或更良性的鼻窦病变区分开来。上颌窦内或延伸至鼻窦的恶性肿瘤所导致的不透射线肿块，很容易与黏液潴留假性囊肿的肿块相混淆。同样，处于早期发展阶段的恶性肿瘤在牙槽突上可产生类似于牙源性炎症的影像学表现。本文报告了1例B细胞淋巴瘤病例。该病变累及上颌牙槽突和鼻窦，在全景X线片上呈现出这样的影像学表现。文中讨论了在建立恶性疾病鉴别诊断时应考虑的影像学和临床特征。
