Huge Cystadenocarcinoma of the Ovary Disguising as Degenerating Uterine Fibroid in Pregnancy: Case Report and Literature Review
Abstract Background: Ovarian malignancy is rare in pregnancy and constitutes 3 – 6% of all ovarian tumours associated with pregnancy. It is usually asymptomatic, detected during routine antenatal ultrasound scan. Treatment is mainly surgical. The aim of this report is to share our experience in the management of a referred case of papillary serous cystadenocarcinoma of the ovary disguising as degenerating uterine fibroid in pregnancy. The diagnostic challenges and treatment are highlighted with a view to improving care in our setting.Case presentation: A 29 year old gravida 2 para 1 with one living child was referred to our unit at 25 weeks gestation with complaint of progressive painful abdominal distension with dyspnoea noticed in the index pregnancy. Ultrasound scans were suggestive of uterine fibroid in pregnancy with degenerative changes for which she had conservative management. Due to worsening symptoms, she had laparotomy and a huge ovarian mass was removed alongside the affected ovary. Histology confirmed Serous Papillary Cyst Adenocarcinoma of the ovary. She is doing well on adjuvant chemotherapy. Conclusion: A high index of suspicion for ovarian malignancies in pregnancy, coupled with complementing MRI (when available) with ultrasound to differentiate degenerating uterine fibroids is suggested/recommended.
