title: Computed tomography findings in acute decompensated heart failure: periportal collar sign and lymphedema in the hepatoduodenal ligament and retroperitoneal space.
abstract: We report two cases that were diagnosed with either acute exacerbation of chronic heart failure or acute decompensated heart failure due to acute myocardial infarction; both cases exhibited computed tomography (CT) findings of the periportal collar sign in the liver and lymphedema in the hepatoduodenal ligament and retroperitoneal space. Both of these signs, particularly lymphedema in the hepatoduodenal ligament and anterior pararenal space, are considered very important CT findings when diagnosing acute decompensated heart failure.
