Hepatic sarcoidosis in patients presenting with liver dysfunction: imaging appearance, pathological correlation and disease evolution
Abstract
We hypothesize that hepatic sarcoidosis is a dynamic process that can lead to cirrhosis and portal hypertension, independent of the course of thoracic disease. Therefore, we assess the imaging appearance and progression of hepatic sarcoidosis in subjects presenting with hepatic dysfunction. An IRB-approved, HIPAA-compliant, single-institution retrospective review identified 39 subjects with sarcoidosis-related liver dysfunction. Clinical information was collected. Two abdominal radiologists analyzed baseline and follow-up imaging studies, scoring features of cirrhosis. Chest CT was also analyzed. At presentation, 23 subjects (59.0 %) exhibited >3 cirrhotic features and 15 (38.5 %) >2 findings of portal hypertension. Of subjects with available follow-up, 57.9 % (19 subjects; mean interval 4.7 years) showed worsening of >3 cirrhotic features (Pearson rho = 0.58; p = 0.009). Parenchymal nodules were uncommon (25.6 %), and most regressed. Although 87.2 % of subjects were diagnosed with thoracic sarcoidosis, there was poor correlation between severity of hepatic and chest disease (Pearson rho = 0.30; p = 0.119). A mean of 7.2 years elapsed between diagnosis of pulmonary and liver involvement. Sarcoidosis may present as liver dysfunc...Continue Reading
