TITLE: Transient Hepatic Attenuation Difference (THAD) due to Portal Vein Thrombosis
There is relatively decreased attenuation involving segments 4a, 4b, 1 and 2 and 3 of the liver. This finding is associated with lack of venous opacification within the middle and left hepatic veins. There is opacification of the right hepatic vein. There is thrombosis of the right portal vein. Hepatic arterial flow is well identified to the right and left lobes of the liver. There is extensive splenic traumatic injury with multiple areas of decreased splenic attenuation involving more than 50% of the spleen, representing laceration of the spleen with hematoma and/or infarction. Splenic vein is identified.
