uncommon, Only few cases of prenatal diagnosis of fetal adrenal bleedi
ng by sonography have been reported. Case: Tn a 28-year-old nulliparou
s pregnant woman, routine sonography performed in 35 + 2 weeks of gest
ational age showed a cystic mass on the upper pole of the right kidney
of a male fetus with normal biophysical profile and Doppler flow indi
ces. Sonographic examination demonstrated a spontaneous remission with
in 3 weeks after uncomplicated vaginal delivery. Conclusion: In the ma
nagement of adrenal gland hemorrhage of the fetus or newborn, control
