原发性鼻腔鼻窦恶性淋巴瘤的CT表现

目的:探讨鼻腔鼻窦恶性淋巴瘤的CT特点。材料和方法:回顾分析14例经病理证实鼻腔鼻窦淋巴瘤的CT表现。结果:鼻腔病灶12例,9例起源于鼻腔前部或鼻前庭,鼻窦腔病灶2例;病灶肿块表现4例,浸润表现3例,混合表现7例,多数(11/14)密度相对均匀;位于鼻窦腔者骨质破坏明显,2例均可见骨质缺损;位于鼻腔者骨质破坏不明显或较轻微,5例可见骨质吸收;病灶易累及邻近结构,6例鼻翼、鼻背部皮肤肿胀,皮下脂肪层消失,3例颊部软组织肿胀。结论:鼻腔鼻窦恶性淋巴瘤CT表现有一定特征性。

CT Diagnosis of Primary Malignant Lymphoma in Nasal Cavity and Paranasal Sinuses

Purpose: To explore the CT features of malignant lymphoma in nasal cavity and paranasal sinuses. Materials and Methods: The CT images of 14 patients with malignant lymphoma in nasal cavity and paranasal sinuses by pathological verification were retrospectively analyzed. Results: The lesions of 12 cases located in nasal cavity and lesions of 9 cases arose mainly from nasal vestibule or anterior part of nasal cavity, lesions of 2 cases located paranasal sinuses. 4 cases had mass effects, 3 cases were infiltrative and 7 cases were mixed. Most of them (11/14)were homogeneous. Both 2 cases located in paranasal sinuses were featured by bone destruction showing bone defects. All 5 cases located in the nasal cavity showed no or mild bone destruction showing bony absorption. The adjacent structures were always involved, 6 cases showing swelling of the skin around noses and obscurity of the subcutaneous fat, 3 cases showing swelling on check. Conclusion: The malignant lymphoma in the nasal cavity and paranasal sinuses has some characteristic features on CT images.
