Abstract
Concurrent pregnancy and papillary transitional cell carcinoma of the bladder are rare. Tumors are often discovered by ultrasound when hematuria is mistaken for vaginal bleeding or during routine obstetrical scans. This patient presented at 14 weeks gestational age with vaginal bleeding,which proved to be hematuria. At 16 weeks a maternal bladder mass was identified during routine obstetrical survey scan. Subsequent removal of mass by urologist showed papillary cell carcinoma of the bladder. This case study emphasizes the need for the sonographer to evaluate total maternal pelvic structures during routine obstetrical scans,vaginal bleeding,or when gross hematuria is present. Cystoscopy and transurethral resection are considered safe treatment during pregnancy depending on trimester and pathology results. Early detection and diagnosis produced a favorable patient outcome in this case study.
