The objective of this review is to summarize the earliest radiological findings of AMC (arthrogryposis multiplex congenital), detail the most frequently affected joints, identify associated syndromes, and expose the radiological findings in children whose therapy was delayed. Read More

Juvenile Idiopathic Arthritis (JIA) is the most common musculoskeletal disorder in children. The temporomandibular joints (TMJs) are involved in majority of cases, and detection of early arthritic changes in these joints relies on contrast enhanced magnetic resonance imaging (MRI). However, with the paucity of evidence and consensus on the normal and pathologic changes in this small but complex joint, interpretation of TMJ MRIs remains to be difficult. This exhibit presents the normal growth related and arthritis related variations in the disease progression in TMJ MRIs of JIA patients. Read More

The tibiotalar joint is the third most common location for osteochondritis dissecans (OCD) lesions, which poses the risk of premature osteoarthritis, and often associates with a history of prior ankle sprains and fractures. Unstable lesions require surgical intervention. A 4-stage radiographic classification system has been previously proposed, but this system has a 50% false negative rate when compared to arthroscopic assessment (reference standard). Recently, MRI and arthroscopic findings have been correlated in adults, but no such validation study has been performed in children. Thus, the purpose of our study was to identify MRI findings that predict instability of OCD lesions of the ankle in children. Read More

The mucopolysaccharoidoses are a varied group of lysosomal storage diseases, uncommon in the general population. The accumulation of gylcosaminoglycans throughout the patient’s body leads to a variety of clinical and imaging manifestations. The osseous finding of these patients are well documented on radiography; however, to our knowledge, the soft tissue imaging findings of these patients have not been previously described. Therefore, the aim of this educational exhibit is to elucidate the soft tissue imaging findings of large joints, focusing on patients with Mucopolysaccharoidsis Type I (MPS I). Read More

In pediatric patients with inflammatory arthritis, steroid injections of the joints are an important therapeutic tool to help augment or avoid systemic steroid treatment. In adult patients, fluoroscopy is often used for diagnostic and therapeutic joint injections. In pediatric patients, ultrasound is an excellent modality for joint injections as resolution is very good for superficial structures, there is no radiation, real time imaging can be performed with non-cooperative patients, and steroid dosage can be maximized in small joints without wasting space in the joint with confirmatory contrast, as with fluoroscopy. Pediatric ultrasound guided joint injections are not commonplace at every radiology practice, but with some training, it can be performed safely and effectively to provide patient care. The purpose of this exhibit is to familiarize the reader with proper technique for ultrasound-guided joint injections. Read More

Van Den Ende-Gupta syndrome (VDEGS) is an extremely rare autosomal recessive disorder with mutation of SCARF2. It is characterized by distinctive craniofacial and skeletal manifestations include blepharophimosis, a narrow nose, malar hypoplasia, deformed ears, an everted lower lip, flexion contractures, camptodactyly, arachnodactyly and dolichostenomelia, while development and intelligence are normal. It needs a regular follow-up with orthopedics because of joint contracture deformity and scoliosis.

Accurate and reproducible sacroiliac joint (SIJ) assessment on MRI in pediatric patients is challenging, often with high inter-observer variation. To facilitate consistent SIJ assessment, numerous scoring systems have been proposed. We sought to systematically review articles that evaluated diagnostic accuracy and reliability of existing MRI-based SIJ scoring systems for the evaluation of spondyloarthropathy in children and adults, and assess their applicability to pediatric patients.
