The ultrasonographic (US) appearance of neonatal adrenal hemorrhage has been described as a mass obliterating the normal contour of the entire gland. In the four cases described, different US appearances were found: In three, the hemorrhage was focal with the uninvolved portion of the gland visualized adjacent to the hemorrhage; in the fourth patient, hemorrhage involved primarily the medulla. Excellent computed tomographic or pathologic correlation with the US appearance was demonstrated. These findings suggest that adrenal hemorrhage should be considered in the differential diagnosis of focal adrenal masses in the neonate.
