Fig. 128.1 MRI of the pelvis. (A) Sagittal T2-weighted image of the pelvis shows a teardrop-shaped T2 hyperintense diverticulum (arrow) arising from the urethra and present anterior to the vagina (note the tampon in the vagina). (B) Axial T2-weighted image shows the T2 hyperintense diverticulum anterior to the vagina. (C) Axial T1-weighted gradient echo image shows the diverticulum to be T1 bright with dark signal from the vaginal tampon.


Radiologic Findings


Magnetic resonance imaging (MRI) of the pelvis with a vaginal tampon in place shows a smoothly contoured lesion that is hyperintense on T1- and T2-weighted images. The sagittal T2-weighted sequence best demonstrates a teardrop configuration extending from the posterior aspect of the distal urethra (Fig. 128.1).


Diagnosis
