Funnel chest (pectus excavatum)-CT
Funnel chest (pectus excavatum), the sternum is depressed so that the ribs on each side protrude anteriorly more than the sternum itself. Posteroanterior radiography also depicts parasternal soft tissues of the anterior chest wall as an area of increased density in the inferomedial portion of the right hemithorax. The severity of the deformity is best quantified with CT.
The “pectus index” can be derived by dividing the transverse diameter of the chest by the anteroposterior diameter. Normal value of this index to be 2.56 (±0.35 SD) and suggested that a pectus index greater than 3.25 necessitated surgical correction.
