摘要
目的研究泪腺淋巴细胞增生性病变的CT和MRI表现及其诊断价值。方法回顾分析10例经病理学证实的泪腺淋巴细胞增生性病变患者的CT及MR影像资料,总结病变影像学表现。结果反应性淋巴细胞增生5例,表现为泪腺体积增大,CT呈均匀等密度,MRIT1WI、T2WI呈低或等信号,1例T2WI呈高信号,增强扫描呈明显强化。非典型性淋巴细胞增生1例,CT表现为双侧泪腺弥漫性增大,密度均匀。泪腺淋巴瘤4例,表现为双侧泪腺弥漫增大。结论泪腺淋巴细胞增生性病变的CT及MRI表现与炎性病变相似,但有助于与泪腺上皮性肿瘤鉴别,并可准确显示病变累及范围。
Objective To investigate the CT and MR findings of lymphadenosis in the lacrimal gland and to assess their diagnostic value.Methods The CT and MR imaging findings of 10 patients with lymphadenosis in the lacrimal gland confirmed by pathology were retrospectively analyzed.Results Five patients with reactive lymphoid hyperplasia demonstrated enlargement of the lacrimal gland,homogenous moderate density on CT,hypointense or isointense signal on T1WI and T2WI（one case was hyperintense signal on T2WI）,and marked contrast enhancement.One patient with atypical lymphocytic infiltrate demonstrated diffuse enlargment of bilateral entire glands,and homogenous moderate density on CT.Four had malignant lymphomas showed bilateral diffuse enlargment of the entire glands.Conclusion The CT and MR findings of lymphadenosis in lacrimal gland were similar to inflammation.CT and MR imaging may contribute to differentiate lymphadenosis with epithelial tumors and may demonstrate the extent of the lesion.
