Maternal bladder cancer diagnosed at routine first-trimester obstetric ultrasound examination.

BACKGROUND

Bladder cancer is exceedingly rare in pregnancy and most commonly presents with gross hematuria.

CASES: We describe two patients with the incidental finding of maternal bladder masses identified during routine first-trimester obstetric ultrasonographic evaluation and an ultimate diagnosis of carcinoma. After referral for urology evaluation and biopsy confirmation of bladder cancer, patients underwent surgical resection during their pregnancies without the need for further treatment and had uncomplicated pregnancy courses.

CONCLUSION

The distended maternal urinary bladder at the time of first-trimester ultrasonographic evaluation offers a unique opportunity for examination and early diagnosis of incidental maternal bladder carcinoma.
