An unusual case of insulinoma in a 51-year-old man demonstrates the difficulties in diagnosing and treating hypoglycemia. From the many laboratory tests and procedures performed, the only findings typical of insulinoma were inappropriate values of plasma immunoreactive insulin in relation to the corresponding values of blood glucose, and these were sporadic. A small beta-cell adenoma in the pancreatic head was the cause of the hypoglycemia.

We report a patient with a papillary fibroelastoma arising from the left ventricular posterior wall. The tumor was detected incidentally during echocardiography undertaken to evaluate aortic stenosis. Possible complication from tumor embolization was avoided by surgical resection during aortic valve replacement.
Postinfarction communication between a left ventricular aneurysm and the right atrium is a rare acquired disease. We report a case of a 72-year-old man who recently had dyspnea on minimal exertion and was found to have left ventricle-to-right atrial shunt by two-dimensional transthoracic echocardiography. This diagnosis was confirmed with transesophageal echocardiography, cardiac catheterization, and angiography. The patient underwent successful repair but died of multisystem failure. This case shows the importance of transthoracic echocardiography for the adequate diagnosis and management of such cases.
