case_images: Pre- and postcontrast magnetic resonance imaging of right olecranon. (a) Axial T1 fat-saturated image demonstrates nonspecific T1 isointense mass-like enlargement of the subcutaneous soft tissues overlying the anconeus muscle along the posterolateral aspect of the elbow. (b) Axial T1 fat-saturated postcontrast image demonstrates central hypoenhancement correlating with T2 hyperintense phlegmonous collection (c). There is intense surrounding enhancement representing inflammation. (c) Axial T2 fat-saturated image demonstrates a 1.1 x 2.3 cm T2 centrally hyperintense, peripherally hypointense, phlegmonous collection with diffuse surrounding T2 hyperintense signal representing edema. The phlegmonous collection extended approximately 8 cm in largest dimension.
