ABSTRACT
Malignant cerebral edema can lead to increased intracranial pressure, rapid deterioration of neurological function, and even the formation of cerebral hernia. It has the characteristics of high mortality and disability rates, and is a common cause of poor prognosis in patients with acute massive cerebral infarction. Early decompressive craniectomy can effectively improve the neurological outcomes of patients with malignant cerebral edema. Therefore, early prediction of malignant cerebral edema is crucial. This article reviews the formation mechanism and related imaging manifestations of malignant cerebral edema, in order to provide reference and assistance for the early diagnosis and reasonable treatment of malignant cerebral edema after massive cerebral infarction.
