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

Abstract

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.
