Sonography and MRI of latissimus dorsi strain injury in four elite athletes.
OBJECTIVE
The objective of this study was to describe the MR and sonographic findings in latissimus dorsi (LD) muscle strain in athletes, and to review the most common injuries described in the literature, most of which are humeral avulsions.


METHODS
Four injuries and two reinjuries of the myotendinous junction of the LD were followed from the day of injury until the return to play. Sonography (US) and MR imaging were performed in each case to confirm the diagnosis and to monitor the healing process.


RESULTS
All cases had acute and isolated pain in the back of the shoulder while performing an eccentric maneuver of the arm and the shoulder. US and MR images demonstrated that injuries were located in the middle and cranial portion of the latissimus dorsi surrounding the myotendinous junction. After rehabilitation, all players played at high level again.


CONCLUSIONS
Isolated lesions of LD are very rare. They can be demonstrated by US and MR images.
