Sports hernia represents a complex clinical and imaging entity. The purpose of the review is to provide a practical imaging approach to this condition. The review includes an overview of the anatomy and biomechanics of sports hernia by means of colour illustrations. The role of imaging, and particularly magnetic resonance imaging, is highlighted.

The forefoot may be affected by a wide variety of pathologies that require imaging. Magnetic resonance imaging is the modality of choice for soft-tissue pathologies and occult bone lesions. Correct imaging protocols and an awareness of anatomy are essential for accurate diagnosis.

Rugby players often sustain high-impact collisions and are therefore at risk of significant traumatic thoracic injuries. Injury to the thoracic cage may be associated with potentially life-threatening sequelae. Player management is often based on the accuracy of the imaging report. The author suggests a combination of computed tomography and magnetic resonance imaging to optimally evaluate the full spectrum of these potentially serious injuries.
Secondary chondrosarcoma : malignant transformation of pre-existing hereditary and non-hereditary cartilaginous lesions : case reportSource: SA Journal of Radiology 18, pp 1 –5 (2014) http://dx.doi.org/http://dx.doi.org/10.4102/sajr.v18i2.703More Less
Secondary chondrosarcoma is a malignant hyaline cartilage tumour originating from a cartilaginous precursor, either osteochondroma or enchondroma. We contrast two different cases of biopsy-proven secondary chondrosarcomas resulting from benign, pre-existing cartilaginous lesions - our aim is to contrast and compare these two benign conditions consisting of multiple cartilaginous lesions - one hereditary and the other non-hereditary - and emphasise their potential for malignant transformation.

Macrodystrophia lipomatosa (MDL) is a rare congenital, but non-hereditary, form of localised gigantism of the fingers or toes. The hallmark of the condition is hypertrophy of all mesenchymal elements in the involved region, with a predominance of fibro-adipose tissue. A clinically subtle case of MDL is presented.

Synovial sarcoma is a malignant, predominantly juxta-articular, soft-tissue tumour representing approximately 10% of all soft-tissue sarcomas. Frequently initially incorrectly diagnosed as a benign lesion, it should be considered as a diagnosis when a young adult patient presents with a calcified juxta-articular soft-tissue mass of insidious onset.

Post-traumatic myositis ossificans (PTMO) is characterised by abnormal heterotopic bone formation involving striated muscle. PTMO is usually associated with trauma and is most common in the second and third decades. An important teaching point is that in the early or subacute phase, clinical and imaging features can mimic a soft-tissue sarcoma. A combination of imaging modalities is required to evaluate the muscle lesion.

The most common injury to the biceps muscle is rupture of the long head of the biceps tendon. A tear can occur proximally, distally or at the musculotendinous junction. Two cases are discussed, in both of which the patients felt a sudden sharp pain in the upper arm, at the shoulder and elbow respectively, and presented with a biceps muscle bump (Popeye deformity).

The lesion resulting from humeral avulsion of the glenohumeral ligament (HAGL) is an important cause of anterior glenohumeral instability and can be seen in isolation or combination with an antero-inferior labral complex lesion. A conclusive magnetic resonance imaging diagnosis is aided when either a joint effusion is present or a contrast arthrography of the shoulder is performed. It is important to be familiar with the J sign as it represents contrast leaking through the defect in the lateral attachment of the joint capsule.

Musculoskeletal radiology in South Africa has shown significant growth in the last decade. This was achieved through advanced educational programmes, international input and significantly improved imaging techniques and equipment - which in turn has enabled musculoskeletal (MSK) radiologists to offer an improved service to referring physicians.
