Methods: Forty-?ve cases of lung squamous cell cancer and 59 cases of lung glandular cancer have gone through pathological con?rmation and all the 104 cases have been put under enhanced scanning on the basis of ?at scanning. The shape and density of the metastatic tumors, encephaledema around the tumors, and the reinforcement change after the enhancement were analyzed. Results: The CT scanning images of all the cases showed that, under ?at scanning, the density of the metastatic tumors to the brain of lung squamous cell cancer was over the slightly-high level and by no means even. Again, under ?at scanning, some 10 cases of metastatic tumors to the brain of lung glandular cancer showed a slightly-high density and some 49 other cases a low density and sack-like low density. Forty-?ve cases of metastatic tumors to the brain of lung squamous cell cancer were with hydroncus while some 30 cases of that of lung glandular cancer were in the same condition. Most of the two types of metastatic tumors, amounting to 97 cases, took place in supratentorial manner, and only 7 cases took place in subtentorial manner. Conclusion: The CT images of metastatic tumors to the brain of lung squamous cell cancer and lung glandular cancer are obviously di?erent from each other. As for the lung squamous cell cancer, the ?at scanning density of the tumor is over the slightly-high level with unevenness. There is relatively obvious reinforcement and obvious hydroncus. As for the lung glandular cancer, the metastatic tumor to the brain shows a low density and sack-like low density under ?at scanning. There is no obvious reinforcement and relatively slight hydroncus.展开更多
