Latissimus dorsi tendinosis and tear: imaging features of a pseudotumor of the upper limb in five patients.
OBJECTIVE
The objective of our study was to determine the imaging appearances of a pseudotumor of the upper limb, latissimus dorsi tendinosis and tear, in five patients and to correlate those imaging findings with clinical history and histopathology.


CONCLUSIONS
Tears or reactive tendinosis of the latissimus dorsi tendon at its insertion on the proximal humerus may present as a pseudotumor. Awareness of the imaging findings may allow accurate diagnosis and conservative management.
