There is a relatively well-defined lobulated subcutaneous soft tissue mass of the posterior aspect of the right shoulder in contact with the deltoid muscle anterolaterally, and infraspinatus muscle anteriory with no intramuscular extension. It is of intermediate signal on T1WI, high signal on T2WI with heterogeneous enhancement, and central necrosis on postcontrast sequences. Restricted diffusion is noted on DWI/ADC.
