    Author: Carroll KW, Helms CA, Speer KP.
    Journal: AJR Am J Roentgenol; 2001 Feb; 176(2):393-7. PubMed ID: 11159080.
    Abstract:
    OBJECTIVE: We describe the MR imaging findings of focal articular cartilage lesions of the superior humeral head and the clinical features in seven patients. CONCLUSION: Focal articular cartilage lesions of the superior humeral head are rare lesions that may cause clinical symptoms and may be easily overlooked on MR imaging. These lesions occur in a particular location (along the superior surface of the posterior humeral head, medial to the expected location of a Hill-Sachs lesion), are caused by trauma, and do not seem to have a specific mechanism of injury. Because of improvements in MR imaging of cartilage, this area of the shoulder should be inspected for this lesion.
