Ferumoxytol leak into a joint effusion of a 13-year old female patient with an osteosarcoma of the proximal right humerus. a Coronal PD-weighted fast spin echo (FSE) image demonstrates an inhomogenous intra- and extra-osseous tumor of the proximal humerus (arrowheads) with joint effusion (arrows). b Corresponding axial PD-weighted FSE image shows tumor joint infiltration (arrows). c Coronal and d axial pre-contrast T1-weighted FSE show a hypo- to isointense joint effusion (arrows). e Coronal and f axial LAVA images after intravenous injection of gadobutrol demonstrates inhomogenous enhancement of the tumor (arrowheads) and the synovia. The effusion (arrows) does not enhance. g Coronal and g axial T1-weighted FSE image at 24 hours after ferumoxytol administration demonstrates T1-enhancement of the tumor (arrowheads) and the joint effusion (arrows)
