肺继发性淋巴瘤的CT诊断

目的　分析肺继发性淋巴瘤的CT和HRCT表现特点 ,表现类型以及分布特点。方法　回顾分析 2 4例经临床或病理证实的肺继发性淋巴瘤的CT表现。结果　肺继发性淋巴瘤的CT表现主要包括支气管血管束增粗、单发和多发结节、肿块样实变及渗出性改变等 5种形式 ,分为肺炎肺泡、结节、支气管血管淋巴管、粟粒和混合型等 5种类型 ,其中混合型最多见 (Ρ <0 .0 5 )。HRCT表现为支气管血管束不规则增粗、肺小叶内结节和实变、肺小叶核增粗和间隔增厚、毛玻璃样改变及囊性变等 7种形式 ,肺内病变分布以双侧、下叶多见 (Ρ <0 .0 5 )。结论　多种表现形式并存是肺继发性淋巴瘤CT表现的重要特点 ,对诊断具有重要价值

CT Diagnosis of Pulmonary Secondary Lymphomas

Objective To study the manifestation,classification and distribution of CT and HRCT in pulmonary secondary lymphomas.Methods CT findings of 24 cases with pulmonary secondary lymphoma proven by clinical or pathology were retrospectively reviewed.Results CT manifestations which consisted of peribronchial or perivascular thickening,single or multiple nodules,massive consolidation and exudative process could be classified into five patterns:pneumonic-alveolar,nodular,brochovascular-lymphangitic,miliary and mixture patterns.HRCT manifestations consisted of peribronchial or perivascular irregular thickening,nodules or consolidation in lobular,thickening of lobular septum or lobular core,ground-glass opacity and cyst.Most of lesions were distributed in bilateral and lower pulmonary.Conclusion Varieties of CT manifestations occurring together is an important feature of pulmonary secondary lymphomas,which is of great value in diagnosing.
