Learning objectives -Understand the embryology of the biliary tract to better comprehend pathologies associated with ductal plate malformations.-Highlight key imaging findings for each pathology through clinical cases.-Show the utility of various imaging modalities to aid in a precise diagnosis.-Exploring differential diagnoses of these pathologies, encompassing other etiologies or in some cases overlapping anomalies.
Read more Background Through a case-based approach, using various imaging modalities including ultrasound, computed tomography and magnetic resonance imaging, a diagnostic approach will be undertaken for pathologies resulting from ductal plate malformations or genetic alterations of the biliary tract.
Read more Findings and procedure details The embryological development of the biliary tract is a complex process closely related to the vascular and parenchymal development of the hepatobiliary system. The ductal plate is the essential structure for biliary tract development; hence, it is crucial to understand the pathologies that can occur as a result of its malformation.These malformations can lead to a spectrum of diseases known as polycystic liver diseases, primarily affecting the intrahepatic biliary tract. However, some disruptions in biliary tract development can also lead...
Read more Conclusion The embryology of the biliary tract is key to understanding ductal plate malformations and the characteristic findings in imaging studies. Early detection of these congenital anomalies is essential for an appropriate multidisciplinary approach, which contributes to better long-term therapeutic outcomes.
