An Unusual Presentation of a Large Cervical Fibroid—Case Report

Uterine fibroids are the commonest pelvic tumors of reproductive-age women, while the incidence of cervical fibroid is only 1–2%. We noted the patient’s clinical history, examination findings, diagnostic tools, management, and outcome. We report a 53-year-old parous lady who was initially diagnosed with malignant ovarian tumor on the basis of clinical manifestations and imaging findings. Intraoperatively, it turned out to be a large cervical fibroid. Total abdominal hysterectomy was performed without any intraoperative complications. Anticipation of complications and preventive measures during surgery are the key of successful outcome in large cervical fibroids. To avoid ureteric injury, preoperative stenting, intra-operative delineation of ureters, and dissection inside the fibroid capsule are the best principles.

Uterine fibroids are the commonest pelvic tumors of reproductive-age women (20%) . Commonly the women with fibroids present with abnormal uterine bleeding, pain abdomen, or palpable mass per abdomen. The diagnosis of fibroid uterus usually made on clinical examination and on ultrasound (USG). USG preferably transvaginal scan is the first-line imaging modality in case of fibroid uterus. It has shown high sensitivity and specificity for the diagnosis . Sometimes this condition is misdiagnosed as adnexal tumor. We present one such case of a large cervical fibroid which was initially misdiagnosed as adnexal tumor.
Though fibroid is the most common pelvic tumors among reproductive-age women (20%), the incidence of cervical fibroid is only 1–2% . Cervical fibroid may develop in both vaginal and supra vaginal part of cervix, but usually develops in the supra vaginal part of cervix. They are classified as anterior, posterior, lateral, and central or multiple according to their site of origin. In the present case, the fibroid was arising from supra vaginal part of posterior cervical wall. Each fibroid presents differently on the basis of location. Most common complaints at the time of presentation are urinary retention, constipation, and menstrual abnormalities, and rarely it may present as palpable mass per abdomen and misdiagnosed as an ovarian tumor . In our case also, the large cervical fibroid was initially misdiagnosed as ovarian tumor. Usually ovarian mass can be easily differentiated from uterine mass on clinical examination. If a groove felt between the mass and uterus on vaginal examination is suggestive of ovarian mass and if no groove is felt, most likely it is a uterine mass. Imaging modalities such as USG, CT scan, or MRI are sensitive to differentiate between uterine and ovarian mass. But diagnostic errors can happen in identification of solid masses . Color Doppler could have been done in present case to differentiate ovarian malignancy from benign mass like fibroid. Color Doppler is reported to be more specific in differentiation of benign and malignant adnexal masses . We did not go for Doppler preoperatively as large cervical fibroid was not kept in differential diagnosis. This is the learning point from this case; one should be vigilant about rare conditions.
Another misleading point in our case was raised value of Ca-125. It is not a specific marker for ovarian cancer, as it is elevated in several benign conditions such as peritonitis, pelvic inflammatory disease, or endometriosis .
Large cervical fibroid is a rare phenomenon, poses surgical difficulties, and has an increased risk of urinary tract injuries and intraoperative bleeding due to distorted anatomy. Sharma et al. reported a case of large cervical fibroid (30 × 26 × 22 cm) which was initially mimicking an ovarian tumor. They encountered ureteric injury during surgery, diagnosed intraoperatively and managed well with ureteric anastomosis . Similar ureteric injury was also managed by Kavitha et al. in a case of huge cervical fibroid (20 × 14 cm) . Another case of a large cervical fibroid (30 × 14 × 10 cm) reported by Basnet et al. , bladder injury was noted during surgery. In addition, they had to ligate bilateral internal iliac arteries in order to achieve hemostasis. In the present case, we were able to complete the surgery without any complication. The idea behind the successful outcome was to remain within the capsule of fibroid and always keep the ureter under vision. Preoperative ureteric stenting is also a good option to avoid ureteric injury. Removal of fibroid before proceeding to hysterectomy is a reasonable and safer alternative.
To emphasize, rare conditions such as cervical fibroid should be kept in mind in cases of solid adnexal masses. Anticipation of complications and preventive measures during surgery are the key of successful outcome in large cervical fibroids. To avoid ureteric injury, preoperative stenting, intra-operative delineation of ureters, and dissection inside the fibroid capsule are the best principles.
Dr. Kavita Khoiwal, Dr. Amrita Gaurav, and Dr. Anupma Kumari have conceived the case report and performed the surgery. Dr. Payal Kumari retrieved and prepared CT scan images and HPE report. Dr. Kavita Khoiwal prepared the figures and wrote the manuscript. Dr. Jaya Chaturvedi guided throughout the patient management as well as in manuscript preparation. All authors read and approved the final manuscript.
