The area measured 9 cm on the oblique axial diameter, almost 3 cm in depth, and over 3.5 cm craniocaudally, with fluid extending inferiorly from the subscapular region overlying the chest wall axially measuring over 5 cm transversely and 1.5 cm in depth on T2-weighted images (Figure 3). This MRI confirmed abscess formation within the subscapularis muscle as the cause of the presentation.
