鼻腔及鼻窦非霍奇金淋巴瘤的CT诊断

CT Diagnosis of Non - Hodgldn Lymphoma in Nasal Cavity and Para - nasal Sinuses

目的：探讨鼻腔及鼻窦非霍奇金淋巴瘤（NHL）的CT特点，提高诊断准确性。方法：回顾性分析24例经病理证实的鼻腔及鼻窦NHL的CT表现。结果：24例中16例位于单侧，8例累及双侧。原发于鼻前庭2例、鼻腔6例、鼻窦9例、鼻腔鼻窦7例。病灶肿块表现15例，浸润表现9例。24例中22例病灶密度相对均匀，2病灶密度相对不均，增强后部分强化。原发于鼻腔的淋巴瘤1例见骨质破坏，原发于鼻窦和鼻腔鼻窦的有6例见骨质破坏；常累及邻近结构。结论：鼻腔鼻窦NHL的CT表现缺乏特征性征象，但有一些相对特异性征象有助于鼻腔鼻窦NHL的诊断。根据CT的相对特征性表现，结合临床，有助于及时诊断该类疾病。

Objective： To explore the CT features of non - Hodgkin＇ s lymphoma （NHL） in nasal cavity and para - nasal sinuses in order to promote the diagnostic accuracy. Methods： The CT images of 24 patients with NHL in nasal cavity and para - nasal sinuses confirmed by pathology were retrospectively analyzed. Re- suits：Among 24 cases of NHL, 16 cases were unilateral,8 cases involved bilateral. 2 cases were primary vesti- bule NHL,6 cases were primary nasal cavity NHL , 9 cases were primary para - nasal sinuses NHL,and 7 cases were primary nasal cavity and para - nasal sinuses NHL; 15 cases showed mass effects, 9 cases were infiltra- tive. Among 24 cases, 22 lesions were homogeneous in density, 2 lesions were not homogeneous, partial rein- forcement in Enhancement Scan. In this group, 1 case showed bone destruction in primary nasal lymphoma, 6 cases showed bone destruction in primary para - nasal sinus lymphoma and nasal cavity and para - nasal sinuses lymphoma; the adjacent structures were often involved. Concluslons：Nasal cavity and paranasal sinuses NHL CT demonstrated lack characteristic manifestations. The NHL in the nasal cavity and para - nasal sinuses has some characteristic features on CT images; CT scan plays an important role in diagnosis of NHL.
