RT Journal A1 Pollack LD, Hall JG T1 POsterolateral (bochdalek's) diaphragmatic hernia in sisters JF American Journal of Diseases of Children JO American Journal of Diseases of Children YR 1979 FD November 1 VO 133 IS 11 SP 1186 OP 1188 DO 10.1001/archpedi.1979.02130110094019 UL http://dx.doi.org/10.1001/archpedi.1979.02130110094019 AB • Two siblings with identical left posterolateral diaphragmatic (Bochdalek's) hernias are described. To our knowledge, there is one earlier description of siblings in which the diaphragmatic defects have been defined as posterolateral. The observation of these two families with a defect that is usually sporadic raises the possibility of etiologic heterogeneity among posterolateral defects of the diaphragm. Although overall recurrence risk is probably small, prenatal diagnosis by ultrasound should be possible and may improve perinatal management in familial cases.(Am J Dis Child 133:1186-1188, 1979)
