    Elbow Imaging in Sport

    Elbow pain is a frequent presenting symptom in many athletes, particularly those participating in overhead throwing sports, because of the high valgus forces placed on the elbow in extension. Standard radiographs can identify fractures or dislocation in the acute setting and also detail unique patterns of disease secondary to chronic overuse.

    In a State-of-the-Art article in the April issue of Radiology (RSNA.org/Radiology), Matthew D. Bucknor, M.D., Kathryn J. Stevens, M.D., and Lynne S. Steinbach, M.D., from the Department of Radiology and Biomedical Imaging, UCSF, review basic anatomy, the mechanisms of injury and imaging techniques related to elbow pain.

    Radiographs of the elbow are recommended to evaluate for possible fracture or dislocation following acute injury. Radiography can also demonstrate the presence of a joint effusion after trauma, suggestive of an occult fracture. In the chronic setting, radiographs can also demonstrate soft tissue calcification, ossification, osteophyte formation, or osteochondral defects, which may suggest tendon or ligament injury as a consequence of repetitive microtrauma.

    MRI is the recommended imaging modality for establishing specific patterns of acute and chronic osseous and soft tissue injuries of the elbow. MRI is also the most sensitive modality for diagnosing lateral epicondylosis, the most common cause of elbow pain, although US can be useful for guiding therapeutic procedures.

    “Many injuries of the elbow presentwith overlapping symptoms, and promptimaging evaluation helps to confirmthe correct diagnosis and facilitateappropriate treatment,” the authors write.

    “Biliary Diseases with Pancreatic Counterparts”: Cross-sectional Imaging Findings

    On the basis of the similarities in the histopathologic findings and the clinical-biologic behaviors of select biliary and pancreatic conditions, a new disease concept, “biliary diseases with pancreatic counterparts,” has been proposed.

    In an article published in the March-April issue of RadioGraphics (RSNA.org/RadioGraphics), Venkata S. Katabathina, M.D., of the University of Texas Health Science Center at San Antonio, and colleagues examine the relationship between certain biliary diseases and their pancreatic counterparts, to explore the proposed new disease concept.

    For both biliary and pancreatic diseases, imaging plays a pivotal role in initial diagnosis, evaluation of treatment response, efficacy testing of novel drugs and long-term surveillance.

    “Knowledge of this unified concept may assist in understanding the pathogenesis of pancreaticobiliary diseases and in the development of novel therapeutic agents,” the authors write.

    Coronal T2-weighted fat saturated (FS) MR image in a 20-year-old male varsity gymnast with an acute hyperextension injury demonstrates a proximal tear of the medial collateral ligament (arrow). A decision was made to treat this injury non-operatively. (Radiology 2016;279;1:12-28:) ©RSNA 2016. All rights reserved. Printed with permission.

    Simultaneous occurrence of peribiliary cysts and chronic pancreatitis in a 55-year-old alcoholic man. Axial contrast- enhanced CT image shows an atrophic pancreas with a dilated main pancreatic duct and calcifications (arrowhead), findings consistent with chronic pancreatitis. The patient also had peribiliary cysts (not shown). (RadioGraphics 2016;36;374–392) ©RSNA 2016. All rights reserved. Printed with permission.
