Weight lifting, although offering substantial health benefits such as improved bone density, muscle strength, and cardiovascular fitness, poses significant injury risks. In this article, we review common weight-lifting injuries associated with specific activities of Olympic lifts, bench press, deadlift, and squat, as well as general weight-lifting injuries.

The widely practiced sport of cycling presents unique biomechanical challenges leading to distinct injury patterns. This review explores the biomechanics of cycling, correlates them with common injuries, and discusses the imaging findings associated with these conditions. We focus on overuse injuries, acute traumatic injuries, and specific pathophysiologic mechanisms underlying these conditions. Emphasis is placed on the role of magnetic resonance imaging in diagnosis and management, highlighting how sport-specific biomechanics influence injury patterns and imaging appearances.

Handball is a high-intensity sport with significant risks of both acute and chronic injuries, particularly in the upper and lower extremities. This review article focuses on imaging findings of upper limb injuries sustained by handball players, with a special emphasis on shoulder, elbow, wrist, and hand pathologies. These injuries are common due to the repetitive throwing actions and frequent physical contact inherent in the sport. We discuss key epidemiological data, biomechanical demands, especially throwing, and review specific imaging characteristics and management strategies for these injuries. Understanding these findings is essential for accurate diagnosis, targeted treatment, and optimization of tailored athlete management. This review will help radiologists and sports medicine professionals identify and manage injuries in handball players, with a focus on the upper extremity.

Gymnastics dates back to ancient Greece and remains one of the most popular sports in the modern Olympics. Due to the extreme forces and ranges of motion required during the various disciplines, injuries are frequent. Additionally, many athletes train and compete during skeletal immaturity that predisposes them to specific injuries. This article briefly reviews some of the more common injuries encountered in the upper limb, axial skeleton, and lower limb in gymnasts with an emphasis on the role of magnetic resonance imaging.

A 22-year-old woman with persistent headaches was diagnosed with a right parietal bone lytic lesion with a sunburst pattern, suspected to be either an intraosseous hemangioma or a Langerhans cell histiocytosis. Five years later, progressively increased skull bone destruction, identification of retroperitoneal and lumbar vertebra lesions, and a biopsy of the skull led to the diagnosis of a retroperitoneal paraganglioma with bone metastases. Genetic testing identified an SDHBmutation. This case underscores the diagnostic challenge of metastases of paraganglioma mimicking hemangiomas and thus delaying appropriate management. · - Skull metastases from paragangliomas can present with a pseudoangiomatous appearance that mimics a hemangioma.. · - The presence of an SDHB mutation is associated with more aggressive forms of paraganglioma with higher rates of metastasis and disease-specific morbidity.. · - Lifelong monitoring for paraganglioma is essential due to the risk of late metastasis, especially bone metastasis..

Anterior cruciate ligament tears represent a prevalent injury in sports that involves rotational movements and rapid changes in direction, such as pivot-contact sports. The anterior cruciate ligament serves as the primary stabilizer of the knee, preventing anterior tibial translation and medial tibial rotation. Although clinical examination is essential for diagnosis, magnetic resonance imaging plays a crucial role in confirming complete tears and evaluating associated injuries, particularly meniscal injuries. Diagnosis relies on both direct and secondary signs that are instrumental in assessing knee laxity and stability. Despite advancements in imaging techniques, challenges persist in using magnetic resonance imaging to distinguish between complete and partial tears, evaluate knee instability, and determine the potential for anterior cruciate ligament healing.

The Société d'Imagerie Musculosquelettique was created in 2008, a merger between the Groupe d'Etude et de Travail en Imagerie Ostéo-Articulaire, which became the MSK subspecialty society of the French Society of Radiology in 1996, and the Groupe des Echographistes de l'appareil Locomoteur. It is a multidisciplinary French-speaking scientific society of 1,500 members (80% radiologists and 20% clinicians), administered by a board of 17 elected members.

Acute ankle sprain including distal tibiofibular syndesmosis injury is the most common lower limb sports injury. In the athletic population, imaging with magnetic resonance imaging plays an important role in the grading of acute ankle sprain but crucially also in the detection of associated injuries, such as bone contusion, osteochondral lesions, fracture, and tendon injury. Accurate diagnosis in the acute phase of injury facilitates surgical decision making, appropriate rehabilitation, and prediction of return-to-play time. This review article examines the medial ligament complex, the lateral ligament complex, and the syndesmosis in detail. It summarizes the normal ligamentous anatomy, mechanisms of injury, and provides imaging examples to illustrate the spectrum of findings in acute ankle sprains.

Fatigue fractures, also known as stress fractures, are frequent overuse injuries among athletes. They result from repetitive mechanical loads that exceed the bone's adaptive capacity, leading to microdamage and eventual fracture. Early and accurate diagnosis, primarily through magnetic resonance imaging, prevents complications and facilitates optimal recovery. This article provides a comprehensive review of the imaging of fatigue fractures.
