Figure 1 Fetus at 32 weeks' gestation. (A, B) Ultrasound showing small kidneys for gestational age and anhydramnios (arrows). (C–E) T2-weighted MRI images confirming these findings, also showing hypointense signal of the lung parenchyma compatible with hypoplasia (arrows).

Figure 2 Fetus at 20 weeks' gestation with bilateral renal agenesis. (A) Ultrasound showing anhydramnios with not exhibiting of renal images (arrows). (B) Coronal ultrasound view with power Doppler not identifying the renal arteries (arrow). (C, D) T2-weighted MRI images confirming anhydramnios and absence of the bladder and kidneys (arrows). In addition, note the significant volumetric reduction of the lungs, which show reduced signal characterizing hypoplasia. (E–G) Facies typical of Potter's syndrome and confirmation of bilateral renal agenesis in autopsy. This figure is available in colour online at http://carjonline.org/.

Figure 3 Male fetus at 20 weeks' gestation with posterior urethral valve. (A, C, E) Ultrasound shows significant bilateral hydroureteronephrosis associated with severe bladder and urethra dilation (arrows). In addition, note acute ascites and diffuse bilateral cortical thinning. (B, D, F) T2-weighted MRI images showing dilatation of the entire urinary tract and posterior urethra (arrows). This figure is available in colour online at http://carjonline.org/.

Figure 4 Fetus at 35 weeks' gestation with left renal agenesis. (A, B) Ultrasound showing absence of kidney in left renal fossa as well as lack of renal artery on this side (arrows). (C, D) T2-weighted MRI images confirming renal agenesis and showing vicariant right kidney (arrows). Images of renal ectopy were not identified. This figure is available in colour online at http://carjonline.org/.

Figure 5 (A, B) Ultrasound showing 2 renal arteries, note bilateral renal ectopy associated with anomaly of rotation and apparent fusion of kidney cortex (arrows). (C, D) T2-weighted axial MRI images of a female fetus showing anomaly of rotation and kidney placement with fusion of the lower poles characteristic of horseshoe kidney (arrows). This figure is available in colour online at http://carjonline.org/.

Figure 6 (A, B) T2-weighted coronal MRI images showing duplication of the bilateral collector system. On the right, accentuated expansion of the upper collector system associated with ureteral dilatation ending in ureterocele. On the left, note the dilation of the lower collector system, probably secondary to vesicoureteral reflux (arrows). (C, D) Note the correlation with the obstetric ultrasound images (arrows).

Figure 7 (A, B) Female fetus at 23 weeks' gestation. Prenatal ultrasound images showed substantial increase in kidney size associated with anhydramnios (arrows). (C, E) T2-weighted MRI images. Note the significant increase in the size and intensity of kidney sign with a loss of the cortical-medullar relationship, in addition to sharp decrease in the lung volume and signal strength characteristic of hypoplasia (arrows). (D) Autopsy confirmed the diagnosis of autosomal recessive polycystic kidney disease (arrows). This figure is available in colour online at http://carjonline.org/.

Figure 8 (A, B) Images of the newborn with autosomal recessive polycystic kidney disease in the first few hours of life. Significant respiratory distress required mechanical ventilation. (C) Chest X-ray showing bilateral pneumothorax (arrows). (D) X-ray of the abdomen showing a decrease in intestinal loops on the sides due to increased renal volume (arrows). The intestinal loops were seen to be medially compressed.

Figure 9 Female fetus at 29 weeks' gestation with bilateral stenosis of the ureteropelvic junction. (A, B) T2-weighted MRI images (arrows). (C) 50-mm slab T image shows significant bilateral pyelocalyceal dilation (arrows). Ureteral dilatation is not visible, suggesting stenosis of the ureteropelvic junction stenosis.

Figure 10 Male fetus at 31 weeks' gestation. (A, B) T2-weighted MRI images show multicystic dysplastic kidney, characterized by voluminous expansive formation composed of multiple nonconnected cysts (arrows). (C) Note the similarity of the image with the anatomical image. This figure is available in colour online at http://carjonline.org/.
