- malignant tumor (primary or metastatic) - especially cholangiocarcinoma but hepatocellular carcinoma is also associated (e.g. following TACE and radiofrequency ablation)
- treated peripheral metastases (e.g. post-chemotherapy, post-radiofrequency ablation)
- hepatic hemangioma (particularly sclerosed hepatic hemangioma)
- hepatic epithelioid hemangioendothelioma
- cirrhosis - confluent hepatic fibrosis
- bile duct necrosis
- pseudoretraction - accessory fissure
- hepatic inflammatory pseudotumor
