Shallowing and disappearance of the cerebral sulci is generally indicative of the presence of cerebral edema.
A shallow, disappearing sulcus is generally detected by imaging tests such as a CT or MRI of the skull. A shallow, disappearing sulcus suggests the presence of cerebral edema in the brain. Common causes include massive cerebral infarction, cerebral hemorrhage, encephalitis, subarachnoid hemorrhage, intracranial infection, and ischemic-hypoxic encephalopathy due to various reasons.
When the sulcus becomes shallow and disappears, due to cerebral edema, the cranial pressure can be increased, and most of the patients will have headache symptoms, in addition, depending on the specific causes of the disease, the symptoms can be different, such as fever, hemiplegia, coma and so on.
When the sulcus becomes shallow and disappears, the patient should seek medical treatment in time to find the cause of the disease and then carry out the relevant treatment.
