Herniation of the abdominal contents into the chest through a diaphragmatic hernia or through a traumatic diaphragmatic tear is not uncommon. The case to be reported here is of special interest because of the rarity of the type of herniation observed, the long delay which preceded the diagnosis, and the unusual fashion in which the clinical and radiological picture simulated cardiac disease. Case Report A 45-year-old white male physician had felt well until May 1946, when he experienced tachycardia, fatigue, and slight dyspnea following moderate exertion. He was overweight and attributed the symptoms to obesity. In 1947 he had an episode of chest pain during exertion in cold weather, which he interpreted as an anginal attack. In 1948, frontal headaches developed. At this time, an enlargement of the cardiac contour was demonstrated roentgenologically, and the patient's past history was obtained. On June 20, 1943, while on service with the Armed Forces in North Africa, he had been in a jeep accident which caused mild cerebral concussion and a fracture of the right clavicle. He also received at that time a heavy blow to the precordial area, producing substernal pain and tenderness which lasted for about six weeks. An electrocardiogram in 1944 was normal. Further roentgenologic study in 1948 and 1949 indicated cardiac enlargement of unknown etiology and the patient was advised by one physician to give up his medical practice and to restrict his activities. From May to September 1950 he was hospitalized elsewhere for extensive observation. Roentgenkymography showed diminished pulsations along the right and left borders of the heart. Venous pressure and circulation times were normal. Bromsulfalein retention was 13 to 15 per cent. No other abnormal findings were elicited. Digitalization was without effect. No definitive diagnosis was reached. Angiocardiography, pericardial paracentesis, and exploratory thoracotomy were recommended but refused by the patient. Admission to the Medical Service of the Veterans Administration Hospital (Bronx, N. Y.) was on Dec. 30, 1950. The pertinent abnormal physical findings included moderate emphysema of the chest, distant heart sounds, a mild diastolic hypertension in both arms (130/95), enlargement of the heart manifested by extension of the cardiac dullness to the anterior axillary line, some enlargement of the liver (two fingers below the costal margin), and a vague “fullness” in the left upper quadrant of the abdomen. A hemogram was normal, as were the sedimentation rate, urinalysis, and serology. Liver function studies showed a thymol turbidity of 8.0 units, and a bromsulfalein retention of 16 per cent, without other abnormalities. An electrocardiogram was normal. A postero-anterior chest roentgenogram (Fig. 1A) showed generalized enlargement of the cardiac contour, while a lateral view (Fig. 1B) showed several radiolucent zones overlying the anterior aspect of the heart just posterior to the sternum.
