There is a fluid defect with echoes involving the 'posterior axillary fold'.
A large retracted muscle belly noted medially and posteriorly (latissimus dorsi).
Echogenic fluid tracks around the proximal anteromedial humerus deep to the pectoralis major tendon.
A 'snap' occurred when the patient tried to give extra bounce while bowling.
There is a complete tear at the myotendinous junction of latoissimus dorsi. The teres major muscle appeared intact on ultrasound, but MRI performed later showed involvement of both muscles (not uploaded, no copyright).
Surgical repair was performed.
