CT multiple enhancement of the brain represents an abnormal CT enhancement scan and is mostly seen in brain tumors, aneurysms, and brain abscesses.
CT enhancement scan refers to the intravenous injection of iodine contrast agent and then CT scan, because the contrast agent moves with the blood flow, the richer the blood flow, the more obvious the enhancement. Enhanced CT without enhancement is generally considered to be encephalitis, edema, cystic degeneration, mild enhancement of enhanced CT is seen in mild inflammation, benign tumors, etc. Moderate enhancement is seen in hemangiomas, vascular malformations, malignant tumors, or high-functioning masses.
Multiple enhancement can be seen in the brain, suggesting that the number of lesions is large, suggesting that it may be brain metastases, multiple hemangiomas and brain abscesses. It is necessary to combine with the site of enhancement, the presence or absence of compression of the surrounding brain tissue, bone destruction, etc. to further clarify the nature.
Multiple enhancement of CT brain should be considered in conjunction with the patient’s condition, and should not rely solely on the results of imaging examinations. If the above abnormalities occur, it is necessary to consult a regular hospital in order to avoid delaying the treatment.
