Overview
Imaging Findings
Several imaging findings can aid in the diagnosis of Noonan syndrome. Plain film chest x-rays are usually normal with cardiothoracic ratio not necessarily indicative of disease severity. Roentgenograms can show pectus excavatum or carinatum. [1] Abdominal ultrasound is usually normal but can sometimes show hepatosplenomegaly or renal abnormalities. [2]
Echocardiography
Echocardiograms can show right ventricular enlargement with mild to moderate increase in the thickness of the free wall of the right ventricle. Left ventricular function is generally normal.
Pulmonary valve recordings can show poor a wave definition.
