Rosai-Dorfman disease in the spleen of a pediatric patient: A case report

Figure 3 Magnetic resonance images of splenic masses. A-E: Magnetic resonance imaging (MRI) images demonstrated mass in upper level of spleen; F-J: MRI images showed mass in middle level of spleen; K-O: MRI images illustrated mass in lower level of spleen. A, F and K: Splenic masses showed low signal intensity on T2-weighted images; B, G and L: Splenic masses demonstrated various signal intensities on T1-weighted images; C, H and M: Splenic masses showed low signal intensity in the late arterial phase; D, I and N: Splenic masses showed persistent low signal intensity in the portal venous phase; E, J and O: Splenic masses showed still low signal intensity in the 5-min delayed phase.
