摘要
目的探讨大细胞肺癌的影像特点。方法回顾性分析74例大细胞肺癌患者的X线片表现,其中36例行CT检查。结果 74例大细胞肺癌的X线片表现为团块状影或结节影68例(91.9%),周围型者44例(59.5%),50例(67.6%)位于上叶,约半数患者可见分叶,平均直径约6.5 cm,支气管气象、空洞、钙化少见;36例CT表现与X线片表现相似,周围可见毛玻璃密度影、肺气肿,23例(62.9%)伴有淋巴结大,约半数患者病灶内可见坏死,增强扫描不均匀强化最多见(50%)。结论影像学检查有助于大细胞肺癌的诊断。
Objective To investigate the imaging features of large cell lung cancer（ LCLC ）. Methods Imaging findings of 74 cases with LCLC proved by pathology were reviewed retrospectively. All patients received X-ray chest film and 36 of them received CT scan. Results 68 lesions（91.9% ） were presented as a mass or nodule in X-ray film. 44 lesions（59.5% ） were peripheral ,50 lesions（67.6% ）located in the upper lobes and about half cases were lobu｜ated. The average diameter of 74 lesions was 6.5 cm. Air bronehogram, cavity and calcification were not often seen. The CT findings of 36 cases were similar to the X-ray findings. Ground-glass opacity and emphysema was found on the peripheral of the lesion. Hilar or mediastinal lymph nodes metastasis were seen in 23 eases（62.9% ）. Necrosis was seen in about half of the cases. Inhomogencous enhancement was mostly（50% ） seen in enhanced CT scan after contrast. Conclusion The imaging findings of LCLC are characteristic to some extent.
