Hematocrit effect

Last revised by Avni K P Skandhan on 16 Nov 2021

The hematocrit effect with fluid-fluid levels is a result of the layering of heavier cellular elements of blood located dependent on a liquid supernatant. It can be seen on CT or MRI. It is most frequently seen in the setting of anticoagulation therapy or coagulopathy. 

On reversal of the coagulopathy; the bleeding will eventually stabilize, the fluid levels disappear and the hematoma gradually resorb.
