Hematocrit effect

The haematocrit 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 stabilise, the fluid levels disappear and the haematoma gradually resorb.
