Blood-fluid level on computed tomography head: a sign of warfarin-associated intraparenchymal hemorrhage.
“Blood/fluid level” represents interface between the plasma and sedimented blood and is defined radiologically as presence of area of low computed tomography (CT) attenuation above and high CT attenuation below a discrete line of separation in an area of intraparenchymal hemorrhage. It is a rare finding seen in association with large clot volume of intraparenchymal hemorrhage. We present a case of warfarin-related intraparenchymal hemorrhage presenting with a classic sign of “blood/fluid level” on CT head with small clot volume.
