Transvaginal Resection of a Bladder Leiomyoma Misdiagnosed with a Vaginal Mass: A Case Report and Literature Review

A Rare Case of Urinary Bladder Leiomyoma Invading Urachal Remnant Managed With Robotic Partial Cystectomy

Leiomyoma is a rare benign tumour of the urinary bladder. Typically, bladder leiomyomas are treated with transurethral resection, which yields favourable results. We present a clinical case of a 29-year-old man with a symptomatic bladder tumour, initially diagnosed on flexible cystoscopy and CT scan. Subsequent transurethral resection and MRI scan confirmed a transmural bladder leiomyoma invading the urachal remnant. The patient was subsequently treated with robotic partial cystectomy. The presentation and management, including imaging and histopathology results, are discussed with a brief review of the literature.

Recurrent atypical leiomyoma in bladder trigone, confused with uterine fibroids: A case report

BACKGROUND

Tumors originating from the posterior bladder wall can be challenging to diagnose because they may mimic a mass from the uterine cervix. Atypical leiomyoma of the bladder trigone is extremely rare, with few reported cases, and requires caution during surgery to avoid damage to the adjacent ureter. Diagnostic surgery and confirmational pathology are essential to assess whether the tumor is malignant and relieve clinical symptoms. Herein, we describe a case of recurrent leiomyoma with focal atypia in the bladder trigone.

CASE SUMMARY

A 29-year-old woman with a uterine fibroid incidentally found at a regular checkup was referred to our hospital. Based on magnetic resonance imaging, either urinary bladder leiomyoma or protrusion of pedunculated uterine cervical fibroid into the bladder was suspected. This leiomyoma in the trigone of the bladder was completely excised by laparotomy, and the patient was discharged without complication. Follow-up outpatient ultrasonography identified tumor recurrence after four years. As focal atypia was identified previously, laparotomy was performed to confirm the pathology. A round solid mass was resected from the posterior bladder wall without injuring either ureteric orifice. This tumor was pathologically diagnosed as a leiomyoma without atypia. Three-year follow-up ultrasonography has revealed no recurrence.

CONCLUSION

Atypical leiomyoma in bladder trigone is rare and could be easily mistaken for fibroid in the uterine cervix. To confirm histopathology, surgical excision is mandatory and regular follow-up is necessary to detect recurrence.

Rare symptomatic bladder leiomyoma: case report and literature review

Bladder leiomyoma is a rare, benign tumour of the bladder. We present a clinical case of a 47-year-old asymptomatic woman with symptomatic bladder leiomyoma. Computed tomography showed well-defined bladder leiomyoma in the right posterior bladder wall. After partial cystectomy, pathology findings confirmed leiomyoma of bladder, and the patient achieved clinical recovery in 8 months. We discuss the relevant recent literature of bladder leiomyoma.
