Female 85 years old Reason: evaluate urethral diverticulum, possible stone History: urethral diverticulum with reportedly palpable hardened area PELVIS:UTERUS, ADNEXA: No significant abnormality noted.BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Diverticular disease of the sigmoid and descending colon.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: There is a 2.0 x 3.4 cm nonenhancing, cystic lesion between the urethra and vagina with a fluid-fluid level (series 16, image 21). This has a somewhat horseshoe-type configuration partially encasing the urethra which it is intimately related to. There is no solid enhancing component. Given the intimate relationship to the urethra this is most compatible with a urethral diverticulum. A Gartner's duct cyst could have a similar appearance however this is felt less likely. Superimposed infection cannot be excluded on the basis of this appearance.
1.3.4 cm cystic lesion between the urethra and vagina containing layering fluid or debris. Given the intimate relationship to the urethra, appearance is compatible with a urethral diverticulum. A Gartner's duct cyst could have similar appearance however this is felt less likely. Superimposed infection cannot be excluded on the basis of the MRI appearance.
