Solid fetal renal masses are a rare finding on antenatal ultrasound, with hydronephrosis and cystic disease of the kidney usually being the most common causes for fetal renal enlargement. Herein we report a case of a solid fetal renal mass which was detected on third trimester antenatal ultrasound scanning. This renal mass was evaluated by MRI in the postnatal period and diagnosis confirmed by histological analysis, after surgical excision. Also discussed are the differential diagnoses and imaging features of other solid fetal renal masses, including congenital mesoblastic nephroma, nephroblastomatosis, renal sarcoma and angiomyolipoma.

Statistics from


  • Contributors FR conceptualised this case after consultation with the lead obstetrician and neonatologist. He was critical in the selection of all images used and the reporting of these images. He also reviewed successive versions of the case ensuring that it is of the highest quality before submission. JD collected the high resolution micrographs and images of the gross pathological specimen used in the case. He chased the final histology report ensuring that the diagnosis of Wilms was confirmed before the case write up was started. He was also key in the literature search and write up of the case. CG acquired consent from the parents of the deceased neonate. She also played an integral part in the literature search and case write up. The patient perspective done by the mother of the decreased neonate was given to CG.
