(a) Longitudinal view: an empty uterus superiorly and pelvic kidney inferiorly (double arrow), free fluid in the cul-de-sac (single arrow). (b) Longitudinal view: an empty uterus superiorly and pelvic kidney inferiorly (double arrow), free fluid in the cul-de-sac (single arrow). (c) Longitudinal view: ectopically located pelvic kidney with color Doppler (single arrow). (d) Transverse view: hypoechoic cystic structure with vascular flow in the left adnexa depicting a tubal pregnancy (single arrow).

A transvaginal ultrasonography (TVS) showed an empty uterus, a small amount of free fluid in the cul-de-sac, and an incidental left pelvic kidney (Figures 1(a), 1(b), and 1(c)). At that time, the beta HCG increased 2673 mIU/mL and a repeat TVS revealed the hitherto diagnosed pelvic kidney, a 3-4 cm mass (Figure 1(d)) in the left adnexa, and an empty uterus with small amount of free fluid in the pelvis.

A 12 cm bulge (Figure 2(a)) was observed on the left at the level of the pelvic brim retroperitoneally, which was consistent with an ectopic pelvic kidney. Also, a 3 cm ruptured left ampullary mass, consistent with an EP, was visualized in a distorted left fallopian tube (Figure 2(b)).
