Study Calcify Metastatic Tumor in Brain of CT

<b<Objective:</b< To study the display of the calcify metastatic tumor in the brain and analyzed the relationship with the idiopthic tumor. <b<Methods:</b< Revise the 20 diseases have idiopthic tumor of body and the calcify metastatic tumor in the brain which have been confirmed with surgery operation and pathology. The patients was aged from 34-83 years. Account CT and contrast-enhanced CT was employed to exam the patients. The idiopthic tumor of body was the cancer of lung, breast cancer, the cancer of the colon or rectum, the osteosarcoma and the cancer of ovary. <b<Results:</b< The calcify metastatic tumor in the brain was showed the calcify nidus in the brain with the routine CT scaning; in the contrast-enhanced CT scanning, it will show the density of the calcify nidus in the brain is rising, and it's edge become clarity, it's figuration become slight bigger than the source. <b<Conclusion:</b< CT is a good technique to show the calcify metastatic tumor in the brain. When CT show the calcify nidus in the brain with a patient who has the idiopthic tumor in the body except the brain, we should take into account whether it is the calcify metastatic tumor.
