CTICasesPseudolesion: Convex Posterior Margin of the IVC
▶ Watch on YouTube — age-restricted, cannot embed here
Imaging findings
On a lateral chest radiograph, an object is noted in the posterior mediastinum with a convex posterior margin, for which no corresponding finding is apparent on the frontal projection. Sagittal CT images reveal this to be the posterior margin of the inferior vena cava (IVC) projecting posteriorly.
Key takeaways
The convex posterior margin of the IVC can be an anatomic variant producing a pseudolesion on lateral chest radiographs, as described in classic literature (Proto monograph, 1979). It should not be confused with pathology.
