Mucinous cystadenoma in a 38-year-old woman with dysmenorrhea. (a) Sagittal transabdominal US image shows a cystic mass with multiple septa (*). (b) Axial contrast-enhanced CT image shows a cystic mass (white *) anterior to the uterus (black *). (c–e) Axial T2-weighted (c), sagittal T2-weighted (d), and sagittal contrast-enhanced fat-saturated T1-weighted (e) images show a cystic mass anterior to the uterus with multiple septa (black * in c and d). Enhancement of the septa is seen (arrow in e). Note the incidental left ovarian endometrioma (arrow in c) and adenomyosis (white * in c and d). (f) Photograph of the gross pathologic specimen shows a multiloculated cystic mass. (g) High-power photomicrograph shows intestinal differentiation of the lining with goblet cells (arrow), typical of mucinous cystadenoma. (H-E stain.)
