Case contributed by Dr Luke Danaher

Presentation

Chest pain

Patient Data

Age: 60
Gender: Male
CT

Axial

A focal density surrounds the right inferior pulmonary vein (RIPV)

"Sling-like" morphology

Attenuation value of 9 HU

It mimics an enlarged lymph node

Case Discussion

Pericardial recesses can mimic mediastinal lymph node enlargement.

This is common superiorly along the origins of the great vessels.

An understanding of the pericardial recess anatomy is important in distinguishing this normal variation from enlarged lymph nodes or soft tissue masses in the mediastinum.

Viewing these structures in 3 plane thin-section imaging as well as density measurements can help identify these normal structures.
