A 2-day-old male baby presented to the emergency department with chest wall deformity. There was no associated history of cyanosis or respiratory distress. Clinical examination revealed asternia (complete absence of sternum) with parchment-like membrane [Figure 1] covering the sternal defect. Visible cardiac contractions were evident through the sternal defect. His systemic examination was unremarkable without any obvious associated anomalies. Subsequently, a computed tomogram of the chest confirmed asternia with normal intrathoracic structures [Figure 2]a, [Figure 2]b, [Figure 2]-c. Other investigations including echocardiography and ultrasonography of the abdomen ruled out associated cardiac or urinary anomalies.

Asternia usually occurs in association with other congenital anomalies, such as in children with Cantrell's pentalogy and Leiber's syndrome. Isolated asternia is extremely rare. Complete failure of fusion of the sternal plates (concentration of mesenchymal cells) in a developing embryo results in asternia., Timing of surgical reconstruction is debatable. However, it is agreed upon that the best time to operate is infancy as the thoracic cage is pliable and the gap is less wide. These children continue to have a benign course due to a lack of syndromic associations. However, long-term follow-up is necessary for the evaluation of cardiorespiratory function.
