Thoracoschisis is a rare congenital anomaly that refers to a congenital fissure of the chest wall. It is frequently accompanied with other congenital defects of the limbs and the abdominal wall as part of the limb-body wall complex, which is exencephaly/encephalocele and facial clefts, thoracoschisis and/or abdominoschisis and limb defects. Isolated thoracoschisis is a rare entity. We present a case of isolated thoracoschisis. A 24-week gestational age boy presented with a 3 cm chest wall defect in the left lateral 10th intercostal space and intestines herniating through the defect. There was no history of maternal drug use during pregnancy. Birth weight was 500 g. He underwent surgery. The intestines were reduced via the thoracic wall defect.
