The persistence of myocardial sinusoids in both ventricles as an isolated anomaly is described. A 21-year-old patient had progressive heart failure considered as cardiomyopathy of obscure etiology. Two-dimensional echocardiography demonstrated channel-like structures in the thickened myocardium of both hypokinetic ventricles. Angiography showed a honeycomblike inner contour in both ventricles. Autopsy proved the diagnosis of persistent sinusoids in a thickened myocardium.

Percutaneous transluminal dilatation of an atherosclerotic stenosis of the superior mesenteric artery was done in a 65-year-old woman with abdominal angina. The patient was relieved of abdominal pain immediately after the dilatation.

During 1986 and 1987, 47 patients with renal cell carcinoma were evaluated preoperatively with CT, angiography and MRI. The preoperative tumor stage (T), lymph node metastases and venous involvement determined with the three methods were compared to the operative and histopathological findings. For T stage, angiography proved less accurate (54%) than CT (64%) or MRI (63%). MRI was found to be superior to CT in assessing lymph nodes, with an overall accuracy of 89% and sensitivity of 100% compared to 77 and 60%, respectively, of CT. For venous involvement CT was overall more accurate (74%) than angiography (65%) or MRI (63%). All three methods expressed a low sensitivity (between 31 and 41%) and a high specificity (between 95 and 100%) for detecting venous involvement. The minimal advantages of MRI compared to its high cost do not justify its routine use. CT remains the method of choice in staging preoperatively renal cell carcinoma.
