[An autopsy case of cardiomyopathy combined with nephrotic syndrome and pulmonary cytomegalic inclusion disease].

A 63-year-old male complained of palpitation and dyspnea. ECG showed paroxysmal supraventricular tachycardia. Echocardiogram revealed asymmetrical thickening of the cardiac septum, and by other clinico-pathological observations, nephrotic syndrome and colon adenoma were detected. For these diseases, steroid therapy and operation were performed, respectively. Ten months later, chest X-ray revealed diffuse abnormal shadow in the bilateral lung fields, and the patient expired due to respiratory distress syndrome. The patient's heart weighted 300g and showed extensive myofibril disarray in bilateral ventricles involving the septal region of the heart. Degeneration and atrophy of the atrioventricular node was seen. In the lungs, organizing pneumonia, old pleuritis, diffuse septal fibrosis and cytomegalovirus infection were demonstrated in the alveolar walls. Kidneys showed slightly sclelotic changes in glomeruli and edema-fibrosis in the interstitium. In this rare case, hypertrophic cardiomyopathy was combined with nephrotic syndrome due to glomerular change, and colon adenoma. The patient died of cytomegalovirus infection in the lungs. The histogenesis of myofibril disarray was discussed in these diseases.
