Background In recurrent/unresponsive vaginal discharge a vaginal foreign body should be considered. Case We present the case of a 13-year-old girl who suffered from a foul-smelling dark brownish and malodorous vaginal discharge since the age of 7 years. When the girl was 11 years old, a foreign body was discovered on ultrasound imaging; removal by colposcopy failed, because of the complete battery inclusion in the posterior vaginal wall. Two years later, at our institution, radiological images yielded the general position of the foreign body; colposcopy showed complete vaginal stenosis. Forced dilatation allowed surgical removal of the battery which was embedded in the vaginal fundal wall. Summary and Conclusion Early removal of foreign objects prevents ulceration, necrosis, stenosis, perforations, and late serious sequelae such as pelvic inflammation and infertility.
