ABSTRACT
A congenital diaphragmatic hernia (CDH) occurs in approximately 1 per 2000 pregnancies. Most CDHs that are recognized in utero are of the Bochdalek type, resulting from a posterior defect in the diaphragm. Morgagni hernias result from an anterior defect and are the least common type of CDH (5%). They are rarely seen in utero. Furthermore, when they are seen in utero, they may be mischaracterized. We present a case of an unusual type of Morgagni hernia diagnosed in utero. The type of Morgagni hernia reported here is particularly uncommon. Two cases with similar findings have been reported previously. The shared findings between these cases indicate that, although rare, this may be a recognizable type of CDH and one that is distinguishable from the Bochdalek type.
