This is the appearance of pediatric appendicitis on MRI. Intravenous gadolinium contrast aids in visualization of the appendix (as seen in the third image above, the LAVA-Flex sequence MRI). MRI has recently been a hot topic of research in the diagnosis of pediatric appendicitis in an effort to reduce radiation to kids, in concordance with ALARA principles.
