Physiological enlargement does not need to be dealt with, while pathologic enlargement needs to be treated with drugs or surgery for the cause of the disease. 1. Physiological enlargement: perivascular gap is the gap formed around small blood vessels when the blood vessels in the brain enter the brain parenchyma and the soft meninges sink into the brain parenchyma, and the perivascular gap is usually shown as an elliptical, round, or tubular structure of less than 3mm in MRI images, with a clearer boundary, which generally does not need to be handled in this case. 2. Pathological enlargement: It is mainly considered to be related to brain tissue lesions, vascular lesions, or tumor growth.
