Radiation encephalopathy and brain tumor have different causes, different clinical manifestations and different imaging manifestations.
1. Different pathogenesis: Radioactive encephalopathy is caused by the radioactive damage to normal brain tissues as a result of patients receiving long-term radiation therapy. On the other hand, the pathogenesis of brain tumor has not been fully explored yet, and ionizing radiation may be one of the risk factors for brain tumor.
2. Clinical manifestations are not the same: both radiation encephalopathy and brain tumor will have the manifestations of cerebral edema, increased intracranial pressure and so on. However, brain tumors usually become more and more serious, whereas these symptoms of radiation encephalopathy will be gradually alleviated after the cessation of radiation therapy.
3. Imaging manifestations are also different: radiological encephalopathy is mostly diffuse damage to brain tissues, while brain tumor is basically focal damage, therefore, when intensified scanning, the former is mostly diffuse enhancement, while the latter is mostly ring-shaped enhancement.
It is recommended that patients with radiation encephalopathy or brain tumor should seek medical treatment in time and under the guidance of doctors, so as not to delay the condition.
