ABSTRACT
Horseshoe adrenal gland is a rare congenital abnormality associated with multiple congenital anomalies that may involve the cardiovascular, central nervous, and genitourinary systems. In this report, we describe the sonographic findings of horseshoe adrenal gland in a newborn with right isomerism a frequently associated cardiovascular anomaly.

In newborn infants, normal adrenal glands are characterized by a relatively thin echogenic center surroundedby a thick, hypoechoic cortical rim as seen on ultrasound (US). Various disorders involving the neonatal adrenalgland include adrenal hemorrhage, hyperplasia, cyst, Wolman's disease, and congenital neuroblastoma. Adrenalhemorrhage is the most common cause of an adrenal mass in the neonate, though differentiation between adrenalhemorrhage and neuroblastoma is in many cases difficult. We describe characteristic US, CT and MR imaging findingsin neonates with various adrenal disorders.
