CTICasesInferior Vena Cava Intramural Hematoma
Imaging findings
CT abdomen shows a well-defined, non-enhancing, hyperdense intramural mass along the anterior wall of the infrarenal inferior vena cava (IVC), without retroperitoneal hemorrhage or adjacent muscle involvement.
Key takeaways
Spontaneous intramural hematoma of the IVC is an extremely rare vascular event, typically occurring in patients on therapeutic anticoagulation. It presents as a focal, non-enhancing hyperdense mural mass that can be mistaken for a tumor or thrombus. Management is conservative with close imaging follow-up.
