PAAG injection complicated with recurrent right breast abscess. Axial MR images of T1-weighted (a) and T2-weighted, fat-saturated (b) sequences depict a T1 hypointense and T2 hyperintense collection (black arrows) at the right breast. It shows rim enhancement after contrast injection (c). A sinus tract (arrowhead) is demonstrated at the lower outer aspect of the collection on the T1-weighted post-contrast coronal image with subtraction (d). Note the T1 low signal (a), T2 high signal (b) PAAG collection without any enhancement at the left retroglandular region (white arrows) (c)
