Magnetic resonance imaging (MRI) findings on admission. MRI shows multiple soft masses measuring a total of 3 × 2 × 2 cm in the anterior portion within the elbow joint (yellow arrow). The lesion is isointense with muscle on T1-weighted MRI (a), and predominantly hyperintense on T2-weighted imaging with fluid effusion in the posterior elbow joint (b). Post-gadolinium sequences show no foci of blooming that would suggest hemosiderin deposition. Thick, peripheral and septal enhancement is seen of not only the masses, but also the whole elbow joint (c).
