Case contributed by Claus Laufenburg


The patient presented with fever and a subjective swelling of the right upper arm.

Patient Data

Age: 40 years
Gender: Female

The MRI showed a partially obstructing intraluminal mass lesion at the inferior vena cava extending through the right subclavian vein with homogeneous high signal on T2 and complete suppression with no enhancement on fat-suppressed T1 post-contrast sequence, in keeping with intravascular lipoma in the superior vena cava. No thrombosis was detected.

Case Discussion

Intravascular lipomas are rare and mostly incidental findings. When detected they are most frequently found in the inferior vena cava (IVC) and less frequently reported in the superior vena cava, brachiocephalic vein, or other periphery veins.
