- Cantrell's pentalogy is a rare congenital malformation involving defects in the thoraco-abdominal wall, diaphragm, sternum, and various heart issues, with cases of it occurring in twin pregnancies being extremely rare.
- This study presents a twin pregnancy where both fetuses were diagnosed with Cantrell's pentalogy, with one fetus displaying multiple anomalies including ectopia cordis and cystic hygroma, leading to a decision for termination after parental consultation.
- The literature review categorizes twin pregnancies with Cantrell's pentalogy into three groups, based on the presence of anomalies in the twins, highlighting the complexity and rarity of such cases.
