The CT of the chest revealed an anterior chest wall deformity with inward depression of the sternum. Haller index measured 13 which is compatible with a severe form of pectus excavatum.
Case Discussion
Haller index is a ratio of the transverse diameter of the chest, divided by the sagittal measure of the distance from the sternum to the vertebral body. A Haller index between 2 and 3.2 is considered a mild deformity; between 3.2 and 3.5 is moderate; 3.5 or greater is a severe deformity.
