1. Identification

1. Chronic subdural effusion: also known as subdural effusion, most of which are related to trauma, and are very similar to chronic subdural hematoma. Some authors even diagnosed that subdural effusion is the cause of chronic hematoma. The identification mainly depends on CT or MRI, otherwise it is difficult to distinguish before surgery.

2. Cerebral hemisphere space-occupying lesions: In addition to hematomas, there are other space-occupying lesions such as brain tumors, brain abscesses and granulomas, which are easily confused with chronic subdural hematomas. The main difference lies in the absence of a history of head trauma and obvious signs of localized neurological deficits. The diagnosis also requires the help of CT, MRI or cerebral angiography.

3. Normal intracranial pressure, hydrocephalus and brain atrophy: These two diseases are similar to each other and similar to chronic subdural hematoma, and both have decreased intelligence and/or mental disorders. However, the above two kinds of lesions have no manifestations of increased intracranial pressure, and imaging examinations are characterized by enlarged ventricles, widened cisterns, and atrophy of brain parenchyma.
