A horseshoe sign is a relatively uncommon imaging finding representing the female urethral diverticulum (UD). While this sign may be appreciated on several different imaging modalities, Magnetic Resonance Imaging (MRI) has high sensitivity and specificity for the detection and characterization of a urethral diverticulum. As shown in Fig. 1, on T2-weighted MR imaging, there is a fluid-filled sac in a curvilinear or horseshoe configuration (Fig. 2), partially wrapping around the urethra.
