playboy sign of ultrasound

Q: What is the playboy bunny sign of ultrasound? 

 Answer: Any cause which results in hepatic congestion - portrays dilated hepatic vessels as a playboy bunny. This includes congestive heart failure (CHF), constrictive pericarditis, pericardial effusion, cardiomyopathy, or right-sided valvular disease involving the tricuspid or pulmonary valve. Hepatic venous congestion combined with inferior vena cava dilatation gave a classic 'playboy bunny' sign on liver ultrasound.
