ALTHOUGH diaphragmatic hernia in general has ceased to be a rare disease, the anterior subcostosternal type (i. e., through the foramen of Morgagni) is unusual. Hedbloom1 stated that about 60 poorly documented cases had been described up to 1938 in a study of 1,003 diaphragmatic hernias of all types. Harrington2 pointed out that 24 instances were reported between 1930 and 1942. Only 5 patients had undergone surgical treatment. In his own series of 270 diaphragmatic hernias there were 4 of the subcostosternal type operated on. In a later article3 the same author added 4 more cases of this type, which made a total of 8 in his personal experience with 404 diaphragmatic hernias.
Subcostosternal hernias or hernias through the foramen of Morgagni have been classified as congenital and acquired. As stressed by Harrington, the constant location of the hernial hiatus, the constant relation of the neck of
