1.
Gross specimen of hyaline cartilage proliferation noted surgically
within distended bursa and superimposed conventional radiograph.
2.
Coronal T1W MR image reveals intermediate signal intensity
mass at medial aspect of proximal tibia.
3.
Axial T1W MR image reveals mass with slight prosterior extension.
Note relationship to tendons of gracilis, sartorius, and semitendinosus
muscles Iarrows). Pesanserine refers to the conjoint tendons
of these muscles, together resembling the foot of a goose (Pes-Foot;
Anserine- Goose).
4.
Contrast enhanced axial T1W MR image reveals fluid content
of mass. In this case a diagnosis of anserine bursitis was offered
prospectively by the radiologist.
5.
Axial FSE T2W MR image reveals high signal intensity lesion
with central low signal intensity focus (arrow) corresponding
to the conventional radiograph.
