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.
Conclusion: 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.
