Data for: Paracaval Lipoma: Case Study and Literature Review

Abstract: Paracaval lipoma refers to a fatty tissue collection surrounding the intrahepatic portion of the inferior vena cava (IVC). It is a rare but benign finding on abdominal CT imaging, speculated to be a result of negative thoracic pressure on the inferior vena cava during inspiration. If not recognized, paracaval lipoma can be confused for thrombus or, worse yet, malignant invasion of the IVC, resulting in a costly and unnecessary workup. Here we describe a 51-year old white male presenting to our institution with a two-week history of abdominal pain, increasing abdominal girth, jaundice and ascites; subsequent CT of the abdomen and pelvis without contrast revealed an incidental finding of fat deposition around the caudate lobe in a juxtacaval distribution, consistent with paracaval lipoma.
