Absent Thoracic Rib |Biomedgrid

Congenital absence of the ribs is relatively rare, and absence of the superior anterior ribs has not yet been Documented [1,2]. we report a full-term Chinese male infant born with the absence of the superior anterior 2nd and 4th ribs on the left side without notable dyspnea. Asymptomatic single rib absence is managed conservatively but for absence of multiple ribs, surgical repair is required, in our unit reported again Preterm 34 weeks with absent 2nd, 3rd and 4th left thoracic ribs without dysmorphic feature admitted in the NICU with respiratory distress, the congenital arrest in the development of the ribs is more frequent than the arrest of formation or the complete absence of the ribs. The arrest of development is generally manifested at the costal cartilages and the anterior parts of the ribs. It does not occur at any constant level. The defect is generally unilateral, and the first rib is usually unaffected.
