Mullerian duct cysts Axial a T1W and (b) T2W images and Sagittal (c) STIR images show a cystic structure with a fluid–fluid level from high signal intensity simple fluid and low signal intensity fluid from haemorrhage. It extends beyond the base of prostate. d Axial and (e) sagittal T2W images show another case with a midline cystic structure (white arrows) with homogeneous high T2 signal which is bulbous at the superior aspect with an inverted droplet morphology inferiorly. The base of the lesion does extend above the level of the base of the prostate gland which is shown by the red arrow. These are in keeping with Mullerian duct cysts
