Abstract

BackgroundPrimary vaginal calculus is rare and often misdiagnosed due to its low incidence. The formation of primary vaginal calculus is mainly due to the pooling and stasis of urine within the vagina, and associated with urogenital tract abnormalities.Case presentationWe present a case of a 23-year-old woman with urogenital sinus anomaly who presented with a vaginal calculus. The patient was not suspected of a calculus in the vagina until the patient suffered amenorrhea and dyspareunia. Pelvic computed tomography (CT) and magnetic resonance imaging (MRI) confirmed the patient had urogenital sinus anomaly with vaginal calculus. For the reason, the calculus was removed by surgery, and the reconstruction of vagina and urethra was performed. The postoperative recovery and follow-up were uneventful.ConclusionsAlthough vaginal calculus and urogenital sinus anomaly are extremely rare in literature, the radiologist should be familiar with the imaging appearance of urogenital sinus anomaly, and be aware of the possibility of vaginal calculus.

Highlights

Primary vaginal calculus is rare and often misdiagnosed due to its low incidence
Conclusions: vaginal calculus and urogenital sinus anomaly are extremely rare in literature, the radiologist should be familiar with the imaging appearance of urogenital sinus anomaly, and be aware of the possibility of vaginal calculus
Primary vaginal calculi are rare disorder which has been reported in association with urogenital tract abnormalities such as urogenital sinus anomaly, urethrovaginal fistulas, vaginal outlet obstruction and bladder exstrophy [1,2,3,4,5]

Summary

Conclusions

Vaginal calculus and urogenital sinus anomaly are extremely rare in literature, the radiologist should be familiar with the imaging appearance of urogenital sinus anomaly, and be aware of the possibility of vaginal calculus.
