title: Case report: maximum-intensity projection and minimum-intensity projection of computed tomography are helpful in the diagnosis of Budd-Chiari syndrome in complicated liver cirrhosis.
abstract: BACKGROUND
  Early detection of Budd-Chiari syndrome (BCS) to give the appropriate therapy in time is crucial. Angiography remains the golden standard to diagnose BCS. However, to establish the diagnosis of BCS in complicated cirrhotic patients remains a challenge. We used maximum intensity projection (Max IP) and minimum intensity projection (Min IP) from computed tomographic (CT) images to detect this syndrome in such a patient.
  
  
  METHODS
  A 55-year-old man with a history of chronic hepatitis B infection and alcoholism had undergone previously a left lateral segmentectomy for hepatic epitheloid angiomyolipoma (4.6 × 3.5 × 3.3 cm) with a concomitant splenectomy. Liver decompensation with intractable ascites and jaundice occurred 4 months later. The reformed images of the venous phase of enhanced CT images with Max IP and Min IP showed middle hepatic vein thrombosis. He then underwent a living-related donor liver transplantation with a right liver graft from his daughter. Intraoperatively, we noted thrombosis of his middle hepatic vein protruding into inferior vena cava. The postoperative course was unevenful. Microscopic findings revealed micronodular cirrhosis with mixed inflammation in the portal areas. Some liver lobules exhibited congestion and sinusoidal dilation compatible with venous occlusion clinically.
  
  
  CONCLUSIONS
  We recommend Max IP and Min IP of CT images as simple and effective techniques to establish the diagnosis of BCS, especially in complicated cirrhotic patients, thereby avoiding invasive interventional procedures.
