Sonographic Diagnosis of Fetal Adrenal Hemorrhage Complicating a Vein of Galen Aneurysmal Malformation.

BACKGROUND

The vein of Galen aneurysmal malformation (VGAM) is a rare intracranial vascular malformation which causes end-organ ischemia or venous congestion due to heart failure. Adrenal hemorrhage associated with VGAM has not been reported in the literature. We present the imaging findings of a fetal VGAM with adrenal hemorrhage.

CASE REPORT: A 26 year-old primigravida woman whose fetus with VGAM and mild cardiomegaly was scanned in the 34th week. On fetal ultrasound, a hyperechoic, well-circumscribed mass in the left suprarenal region was shown. Fetal and postnatal magnetic resonance imaging confirmed the diagnosis of adrenal hemorrhage. The baby died after delivery.

CONCLUSION

Adrenal hemorrhage can complicate VGAM in fetuses with severe heart failure. Evaluation of the adrenal gland in affected cases may contribute to the prenatal counseling, and postnatal management.
