Female urethral diverticulum is a localized out-pouching of the urethra that is becoming increasingly prevalent, but often poses a diagnostic challenge. Traditionally, conventional voiding cystourethrography has been used to make the preoperative diagnosis. With the development of higher-resolution images acquired through ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI), the anatomy and various abnormalities of the female urethra can be better elucidated. This article focuses on the imaging features of female urethral diverticulum, with emphasis on diagnostic pearls, particularly using MRI. Female urethral diverticulum can be best identified by their location in the posterolateral urethra and by their communication with the urethral lumen. Improved imaging techniques combined with increased physician awareness of urethral diverticulum will lead to more prompt and accurate diagnosis of this entity, leading to better treatment of affected patients.
