BACKGROUND: Degenerating myomas are common explanations for pain associated with abdominal masses in pregnancy. However, masses arising from other pelvic organs should be included in the differential diagnosis.
CASE: We present a case of an abdominal mass in pregnancy that was originally misdiagnosed as a uterine leiomyoma. Attention to the patient's history along with judicious use of imaging modalities led to the correct diagnosis of urachal duct carcinoma. This was treated appropriately and resulted in a term vaginal delivery. We present a review of the literature on this tumor and its management in pregnancy.
CONCLUSION: Urologic malignancies are rare but should be considered in the differential diagnosis for any woman presenting with pain and an abdominal mass in pregnancy. A multidisciplinary approach optimizes outcomes.
Although rare, urologic malignancies should be considered in the differential diagnosis for any woman presenting with pain and an abdominal mass in pregnancy.
