EP06.23: Fetal adrenal cyst: challenges in prenatal counselling

Abstract

Background: fetal abdominal cysts constitute a variety of possible etiologies. Parents are often eager to have a clear diagnosis. We report a case of a 28 years old G1 P0 with no particular history. The first trimester NT was normal. A biochemical screening was reassuring. Diagnosis of a 7 mm right renal cyst was done at 22 weeks by an ultrasonography done outside of our facility. Morphology scan did not reveal any other associated abnormalities. The patient came for a second opinion exam at 26 weeks. The cyst increased in size during ultrasound follow-up to reach 9 mm. It was located at the suprarenal but was distinct from the kidney and was probably of adrenal origin. The latter seemed increased in size reaching 17 1,*5mm. Colour Doppler was not in favour of sequestration. Heart rate, umbilical and cerebral Doppler were within normal. Biometry was at the 50th percentile. Possible diagnosis of a renal cyst, neuroblastoma, adrenal cyst were the major possibilities discussed with the patient along with the respective outcomes. MRI is a useful tool to differentiate between all these diagnoses, along with the ultrasound follow-up. Fetal adrenal cyst is difficult to differentiate from neuroblastoma. Other diagnostic tests and follow-up are mandatory during pregnancy.
