Summary
CT scans revealed unique signs of right heart failure, including unusual liver enhancement patterns and fluid buildup. Recognizing these findings as passive hepatic congestion is crucial for accurate diagnosis and avoiding misinterpretation of liver masses.
Area of Science:
- Radiology
- Cardiology
- Hepatology
Background:
- Right heart failure can lead to complex systemic effects.
- Accurate interpretation of imaging findings in heart failure is essential for patient management.
- Computed tomography (CT) is a key diagnostic tool in evaluating cardiac and hepatic conditions.
Purpose of the Study:
- To describe unusual CT findings associated with right heart failure.
- To identify imaging patterns indicative of passive hepatic congestion.
- To differentiate these findings from focal hepatic lesions.
Main Methods:
- Retrospective analysis of seven patients with clinical right heart failure.
- Review of bolus-enhanced CT scans, focusing on hepatic enhancement patterns.
- Correlation of CT findings with clinical presentation and ancillary signs.
Main Results:
- Observed retrograde hepatic venous opacification during early contrast scans.
- Identified diffusely mottled hepatic enhancement during the vascular phase.
- Ancillary findings included cardiomegaly, pleural effusions, ascites, and intrahepatic perivascular radiolucency.
Conclusions:
- The described CT abnormalities are attributed to passive hepatic congestion secondary to right heart failure.
- This pattern of hepatic enhancement can mimic or obscure focal hepatic masses on dynamic CT.
- Recognizing passive hepatic congestion aids in explaining liver function abnormalities in heart failure patients and prevents diagnostic errors.
