肺内淋巴瘤的影像诊断

目的 研究肺淋巴瘤和肺假性淋巴瘤影像表现及诊断价值。方法 8例肺淋巴瘤均行X线胸片、腹部B超或CT检查，其中6例行胸部CT、2例行气管分叉体层和肺内病灶体层检查；2例肺假性淋巴瘤均X线胸片、气管分叉体层及肺内病灶体层检查。均经病理证实。结果 8例肺淋巴瘤均表现为单发或多发肺结节、肿块，7例病灶边缘呈棉絮状或周围呈磨玻璃样，2例灶内可见支气管气像，1例可见空洞。2例合并有双肺多发斑片，2例合并双肺细网状结构或磨玻璃样变，1例合并双肺多发粟粒结节。2例肺假性淋巴瘤表现为含支气管气像的双肺多发大片浸润实变，无纵膈、肺门淋巴结肿大。结论 肺淋巴瘤影像表现多样，结节或肿块型的病灶边缘棉絮状或其周围呈磨玻璃样，多合并肺内斑片、肺间质变。但最终诊断依靠病理。

The radiographic findings in diagnosis of pulmonary lymphoma

Objective To study the radiographic findings in the diagnosis of pulmonary lymphoma and pseudolymphoma. Methods Eight patients with pulmonary lymphoma and 2 with pseudolymphoma were examined by X ray film, tomography, and CT. Results Single or multiple nodules or masses were observed in 8 patients with pulmonary lymphoma, shaggy borders or halo of ground glass attenuation in 7 patients, 2 patients had multiple patchy infiltrates bilaterally, 2 had diffuse interstitial infiltrates and 1 had miliary nodules. Multiple consolidations with air bronchogram and without hilar and mediastinal lymphadenopathy were observed in 2 patients with pulmonary pseudolymphoma. Conclusion Radiographic findings of pulmonary lymphoma were varied, the most common findings were the nodules or masses with shaggy borders or halo of ground glass attenuation. The specific findings of pulmonary pseudolymphoma were multiple consolidations with air bronchogram and without hilar and mediastinal lymphadenopathy. The final diagnosis relied on pathology.
