Protrusion of the sternal body and xiphisternum. No suspicious osseous or retrosternal lesion. Features are consistent with pectus carinatum. 

Case Discussion

Pectus carinatum or “pigeon chest” is characterized by an abnormal prominence of the sternum. This condition commonly affects males around puberty when their growth spurt occur. In our case, the chest protrusion became more apparent as the patient underwent some weight loss.

Severe cases of pectus carinatum may result in restricted lung volume and inefficient respiration, necessitating treatment eg. orthotic bracing and minimally invasive surgery.
