Cavernous transformation of the portal vein (CTPV) is characterized by the formation of venous channels within and around a previously stenosed or occluded portal vein, serving as portoportal collateral vessels. It is a major cause of portal hypertension in children and requires a multifaceted management approach, including medical therapy, interventional procedures such as portal recanalization, and surgical treatments ranging from shunt creation to liver transplantation in end-stage cases. CT-angiography, in combination with portal venography, is the key imaging modality for determining the optimal treatment strategy. It is essential not only for assessing liver cirrhosis and secondary signs of portal hypertension—such as portosystemic collaterals, splenomegaly, and ascites—but also for providing detailed anatomical mapping critical for surgical planning. This presentation will illustrate various pediatric cases of CTPV and discuss the optimal management approach based on factors including the presence or absence of liver cirrhosis, dominant portal collaterals, intrahepatic portal flow, proper superior mesenteric vein communicating with the porta hepatis, and splenorenal shunts, among others. For each scenario a therapeutic plan will be suggested based upon clinical and imaging criteria. By the end of this presentation, readers will be able to: Optimize CT protocols for evaluating CTPV; enhance reporting using a structured checklist of key findings; and support clinical decision-making in collaboration with multidisciplinary teams.

Background: With the increasing use of advanced imaging techniques in pediatric populations, incidental findings—particularly pulmonary nodules—are being detected with greater frequency. While many of these nodules are benign, their discovery often leads to clinical uncertainty, additional imaging, and potential anxiety for patients and families. Unlike in adult patients, for whom the Fleischner Society guidelines for incidental pulmonary nodules are well-established, pediatric-specific recommendations remain limited. Objective: This educational poster aims to provide a comprehensive overview of incidental pulmonary nodules identified on pediatric chest imaging. It seeks to guide radiologists in evidence-based decision-making regarding the evaluation, follow-up, and management of these findings. Content Organization: The poster is structured into the following key sections: Epidemiology and Etiology: Overview of the prevalence and common causes of incidental pulmonary nodules in children, including infectious, inflammatory, and neoplastic etiologies. Imaging Characteristics: Description of typical imaging features on chest radiographs and CT scans that help differentiate benign from potentially malignant nodules. Current Guidelines and Limitations: Review of existing guidelines and literature. Discussion of recent efforts to develop pediatric-specific protocols. Risk Stratification and Management Algorithms: Presentation of proposed algorithms for managing incidental nodules based on size, morphology, patient age, clinical history, and risk factors. Radiologist’s Role and Communication Strategies: Emphasis on the importance of clear reporting, interdisciplinary collaboration, and effective communication to reduce unnecessary interventions and anxiety. Future: Review the potential use of new techniques (Photon-counting CT, MR) in this context. Conclusion: The detection of incidental pulmonary nodules in pediatric imaging presents a diagnostic challenge. Through a structured, evidence-informed approach, radiologists can play a pivotal role in guiding appropriate management, minimizing harm, and ensuring optimal patient care. This poster aims to empower radiologists with practical tools and knowledge to navigate these increasingly common findings. Read More
