Imaging Findings

An MRI performed 6 weeks from the start of symptoms demonstrated extensive edema surrounding the teres minor myotendinous junction and tendon (Figure 1). There was an associated high-grade partial-thickness tear of the teres minor tendon (Figure 2). Accompanying reactive humeral subcortical edema at the teres minor tendon insertion was also noted (Figure 2).
