A 37-year-old G3P2, with two prior Caesarean sections, was referred with hematuria in
17
pregnancy. The patient endorsed longstanding dysmenorrhea and catamenial hematuria.
18
Transabdominal ultrasound showed an avascular 4.3x1.7x3.2cm mass arising from the posterior
19
bladder wall (Panel A) with papillary projections extending into the bladder (Panel B and Video).
20
The placenta was fundal. Cystoscopy at 10 weeks gestation confirmed an exophytic mass
21
distorting the bladder trigone. Biopsy was consistent with endometriosis. Mass size and
22
appearance remained unchanged on serial ultrasounds.
23
Repeat cystoscopy at Caesarean confirmed the previous findings (Panel C and Video)
24
with no evidence of other pelvic endometriosis. At 6 weeks post-partum, the patient started
25
oral progestin.
26
Endometriosis is more common in women with previous uterine surgery and should be
27
considered in the differential diagnosis of bladder mass in pregnancy. Biopsy is safe and
28
necessary to exclude malignancy. Masses should be followed serially until they can be safely
29
treated postpartum.
