Abstract
Juvenile idiopathic arthritis (JIA) is a heterogeneous disorder affecting children < 16
years of age. The clinical heterogeneity translates to imaging, where no specific
joint is affected. This article highlights a general imaging approach to JIA, using
specific examples of the knee, hand, and wrist as the typical joints affected. We
then focus on unique joints that are commonly affected by JIA: the temporomandibular
joint, the joints of the upper cervical spine, and the sacroiliac joint. For these
latter anatomical sites, regional anatomy and development, location-specific imaging
considerations, and arthritis, treatment decision making, and potential differential
considerations are reviewed. We highlight, where applicable, a multimodal approach
to imaging using developed or developing standardized scoring systems.
