Bladder endometriosis with intrinsic involvement in a 35-year-old woman with dysuria, hematuria and urinary incontinence during menses. (a) Sagittal and (b) oblique axial T2-weighted images show a mural mass with low signal intensity infiltrating the posterior bladder wall (white arrows). On (c) axial T2* image punctate signal voids due to hemosiderin deposition can be seen along the borders of the lesion (white arrow). On (d) sagittal and (e) oblique axial fat-suppressed T1-weighted images the implant displays intermediate signal intensity with spots of high signal intensity, representing hemorrhagic content (white arrows). (f) Oblique axial MIP image (acquired about 10 min after contrast administration) demonstrates the relationship between the lesion and the ureters (white arrowheads)
