Extrauterine leiomyoma is a rare benign tumor, originating from smooth muscle cells, most often localized in the uterus. Extrauterine localization of leiomyoma is extremely rare. The presence of a neoplasm near the urethra always poses a challenge for differential diagnosis. Variety of pathologies sharing similar clinical findings requires further diagnostic testing and doctor alertness.

The patient underwent neoplasm removal with further histologic examination revealing urethral leiomyoma. The article features the diagnosis and treatment of this rare pathology.

Imaging of the female urethra

Female urethral pathology can be challenging to diagnose clinically due to non-specific symptoms. High-resolution MRI has become a powerful tool in the diagnosis of urethral lesions and staging of malignancy. Additionally, dynamic MRI, fluoroscopy or ultrasound can evaluate for pelvic floor prolapse and the effectiveness of surgical interventions. This article will review the imaging features of common benign and malignant conditions of the female urethra including diverticula, benign cystic and solid lesions, malignancy, surgical slings, and injection of bulking agents.
