Learning objectives: To describe the imaging features of portal vein thrombosis (PVT) and the wide spectrum of associated entities To illustrate the imaging keys that are helpful in differentiating malignant from non malignant PVT To summarize the follow up and potential complications after the diagnosis of PVT is estab[...]

Background: INTRODUCTION: Portal vein thrombosis (PVT) may be caused by multiple abdominal and systemic pathologies. Imaging methods are the mainstay of its diagnosis as the clinical presentation is often nonspecific.    Ultrasound is a very helpful tool, though CT and MRI allow a better depiction o[...]

Findings and procedure details: KEY IMAGING FEATURES Our role as radiologists is essential in the diagnostic of PVT.     Longitudinal extension of the thrombus, grade of luminal obstruction and potential extension to the splenic and/or superior mesenteric vein shouldn’t be missed on our report (Fig. 4).   Tum[...]

Conclusion: PVT is the result of multiple and distinct etiologies and its clinical presentations is often subtle. Radiologists role is essential in the detection and surveillance. Imaging methods allow to establish an accurate diagnosis (tumoral, non tumoral, cirrhotic vs. non-cirrhotic patient, concomitant abd[...]
