Hepatic capsular retraction is a distinctive radiological finding that can indicate a spectrum of underlying hepatic conditions. We aim to explore the knowledge and tools necessary to confidently navigate the realm of hepatic capsular imaging and arrive at accurate differential diagnoses.

Educational Goals / Teaching Points
Review the anatomy of the hepatic capsule. Discuss the various pathologies associated with hepatic capsular retraction, highlighting their distinct imaging features and clinical presentations. Explore cases and scenarios that demonstrate the diverse spectrum of diseases linked to hepatic capsular retraction.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
In this educational exhibit, we explore the causes of hepatic capsular retraction and its diverse differential diagnoses using multimodality imaging. From benign tumors such as hepatic hemangiomas and focal nodular hyperplasia to malignant neoplasms such as cholangiocarcinoma and metastatic tumors, we will discuss distinct imaging features and clinical contexts. Other than neoplastic causes we also include inflammatory, infectious, fibrotic, and chronic liver diseases, including less common etiologies such as amyloidosis and hydatid cysts, emphasizing the importance of recognizing atypical presentations. Throughout interactive case studies, we will bridge clinical correlations and decision-making processes.

As radiologists, a grasp of the myriad differential diagnoses associated with hepatic capsular retraction is paramount. By navigating through the diverse spectrum of benign and malignant entities, inflammatory and fibrotic causes of hepatic capsule retraction, radiologists can contribute significantly to patient management and treatment strategies.
