title: Miscellaneous conditions of the shoulder: anatomical, clinical, and pictorial review emphasizing potential pitfalls in imaging diagnosis.
abstract: The purpose of this article is to review the key imaging findings in major categories of pathology affecting the shoulder joint including hydroxyapatite deposition disease, rotator cuff interval pathology, acromioclavicular joint pathology, glenohumeral osteoarthrosis, and synovial inflammatory processes, with specific emphasis on findings that have associated pitfalls in imaging diagnosis. The pathophysiology and clinical manifestations of the above mentioned categories of pathology will be reviewed, followed in each section by a detailed pictorial review of the key imaging findings in each category including plain film, computed tomography, and magnetic resonance imaging findings as applicable. Imaging challenges that relate to both diagnosis and characterization will be addressed with each type of pathology. The goal is that after reading this article, the reader will be able to recognize the key imaging findings in major categories of pathology affecting the shoulder joint and will become familiar with the potential pitfalls in their imaging diagnosis.
