Rpt MRI 4 wk after surgery at 30/40 gestation for persisting pyrexia
Intrauterine pregnancy confirmed but not interrogated in detail. There are multiple pockets of fluid within the deep pelvis, as well as a 10 cm thick-walled collection in the right lower quadrant, confirming the presence of intra-abdominal abscesses. The large abscess compresses the right ureter against te right psoas muscle, mimicking the physiologic hydronephrosis of pregnancy usually caused by the gravid uterus causing this compression.
