Abstract

Temporomandibular joints (TMJ) are frequently involved in children with juvenile idiopathic arthritis (JIA), and gadolinium-enhanced magnetic resonance imaging (MRI) is the only modality for an early diagnosis. However, only very few data exist on the appearance of contrast-enhanced MRI of normal juvenile TMJ. To define the spectrum of normal MRI findings of juvenile TMJ, and to assess a possible overlap with findings typical for active synovitis in JIA. 96 children (192 TMJ), 51 boys and 45 girls with a median age of 7.8 years (range 3-13 years), underwent a head MRI. The presence of autoimmune disease, including JIA, was excluded via chart history, available laboratory findings, and the absence of known typical pathological MRI changes (degree of synovial enhancement, hyperintense signal on T2-weighted images in the synovia or bone marrow, and morphologic changes of the mandibular condyle) of the TMJ affected by JIA. In 90 (94%) children, the TMJ showed no MRI abnormalities compatible with arthritis. In three children (3%), the only abnormal MRI finding was a small bilateral joint effusion. A further three children (3%) had a mild synovial enhancement seen on both axial and coronal MR planes in one child and only in the axial...Continue Reading

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
