“…MRI may be helpful in the early diagnosis of a suspicious lesion. Inflammatory enthesopathies and apophysitis are difficult to distinguish from infectious lesions in these locations even on an MRI scan [12]. A CT scan clearly defines the presence of a sequestrum in the osteomyelitic cavity.…”

“…This process, coupled with the increased muscular strength and more intense physical activity during early adolescence, predisposes pediatric patients to injury (45). Thus, although the myotendinous junction is the weakest part of the musculoskeletal unit in adults, the physis is the weakest link in children and is a common source of injury (46). In this section, we outline those injuries that can involve the physis.…”

“…MR images typically show enlargement of the apophysis, with T2 hyperintense edema and enhancement in the bone, tendon, physis, and surrounding soft tissue. A linear T2 hyperintense signal between the apophysis and physis suggests the alternative diagnosis of acute avulsion fracture (46).…”

With increasing participation and intensity of training in youth sports in the United States, the incidence of sports-related injuries is increasing, and the types of injuries are shifting. In this article, the authors review sports injuries of the lower extremity, including both acute and overuse injuries, that are common in or specific to the pediatric population. Common traumatic injuries that occur in individuals of all ages (eg, tears of the acetabular labrum and anterior cruciate ligament) are not addressed, although these occur routinely in pediatric sports. However, some injuries that occur almost exclusively in high-level athletes (eg, athletic pubalgia) are reviewed to increase awareness and understanding of these entities among pediatric radiologists who may not be familiar with them and thus may not look for them. Injuries are described according to their location (ie, hip, knee, or foot and ankle) and pathologic process (eg, apophysitis, osteochondritis dissecans). Examples of abnormalities and normal variants of the anatomy that are often misdiagnosed are provided. The injuries reviewed represent a common and growing subset of pathologic processes about which all pediatric and musculoskeletal radiologists should be knowledgeable. Understanding physeal injury is especially important because missed diagnoses can lead to premature physeal closure and osteoarthritis. RSNA, 2016.

“…Proliferation and hypertrophy of the chondrocytes and infl ammatory cells are found at the physis. Infl ammation affects the apophysis itself and extends into bone marrow and adjacent structures (Arnaiz et al 2011 ). Apparent physeal widening, apophyseal edema, and adjacent muscle and bone edema can be seen on MRI and US (Fig.…”
