Multiple diaphragmatic hernias in the unilateral diaphragm are extremely
rare. The authors report a neonate with diaphragmatic hernias through two
defects in the right diaphragm: a posterolateral defect without a hernia
sac and an anterolateral defect with one. After excision of the anterolateral
hernia sac, each defect was closed. Histology studies showed extralobar
pulmonary sequestration in the removed hernia sac. The presence of sequestrated
pulmonary tissue indicates the possibility of interference with the closure
of the pleuroperitoneal canal and muscularization in the diaphragm, which
may result in multiple defects.
