MRA Mapping and Selective Embolization of a Large Uterine Cavity Pseudoaneurysm at 20 Weeks of Gestation

Figure 4

Coronal T1 MRA and 3D surface rendered reconstruction (Vital Images® postprocessing software) of the aberrant right ovarian artery branch feeder at 19 weeks of gestation. The proximal right ovarian artery originates from the aorta and courses into a tangle of vessels (long arrows) in the right abdomen ((a) and (c)) before penetrating the myometrium (curved arrows) ((b) and (c)) and extending caudally (short arrows) as an arcuate artery to the lesion. Pseudoaneurysm (arrowhead), uterine cavity (chevron), and aortoiliac vessels. Draining vein (blue).
