Marked enhancement is not necessarily a malignant tumor. Obvious enhancement is a result of clinical imaging, can be used as a means of determining the nature of the tumor, but is not conclusive, may be inflammatory lesions, vascular lesions and other benign diseases, may also be caused by malignant lesions, there is no way to be 100% sure, but also need to improve the enhancement of the CT, pathological tissue biopsy. In addition, for patients with highly suspected vascular lesions, it is not recommended to carry out puncture test casually and frequently, otherwise it may lead to aggravation of the condition, and it can be clarified through other enhanced examinations. If malignant tumor is identified, radical surgery, radiotherapy, chemotherapy and other means of treatment should be taken in time.
