Imaging for Management of Chronic Subdural Hematoma: A Review

Radiologic imaging has become integral in not only the detection and diagnosis of subdural hematoma (SDH) but also in guiding potential treatment options. This is especially true for chronic SDH, which has conventionally been managed via surgical drainage, but can now be treated with embolization of the middle meningeal artery (MMA). We review the imaging manifestations of SDH as a function of chronicity and standardized methods of measurement and identify the MMA and its clinically significant variant anatomy as it pertains to embolization planning. Equipped with a more comprehensive approach to characterizing SDH, the radiologist will be able to curate findings of greater utility to the clinician.
