Hepatic sarcoidosis in patients presenting with liver dysfunction: imaging appearance, pathological correlation and disease evolution.

• Patients often present with elevated liver function tests indicating cholestasis. • Patients may present with portal hypertension, and some progress to cirrhosis. • Though biopsy can be considered for focal liver lesions, most will regress. • Extent of intra-abdominal involvement may not correlate with severity of thoracic disease. • Liver disease may manifest alongside, prior to or significantly after initial diagnosis.
