Sarcomas of the breast are rare. The radiological and thermographic features of a mixed malignant chondro- and osteoplastic tumour (osteochondrosarcoma) are described. Mammographically, there was rapid growth of nodular, round smooth tumour, with coarse, confluent and bizarre calcification. Thermography revealed the features of malignancy. In the differential diagnosis, a circular focus with coarse calcification, as occurs in a sarcoma, may be difficult to distinguish from a fibro-adenoma. Such lesions should therefore be removed as soon as possible and submitted to careful histological examination.

Echocardiographic features of total anomalous pulmonary venous connection.

Seven patients, four months to ten years of age, with total anomalous pulmonary venous connection (TAPVC) were studied by echocardiography. The diagnosis was confirmed by cardiac catheterization, angiography, and surgery in each. The connection was to the left vertical vein in four patients, to the coronary sinus in one, to the inferior vena cava in one, and directly to the right atrium in one. All patients exhibited the echocardiographic criteria of right ventricular diastolic volume overload (RVDVO). In addition, an echo-free space was identified dorsal to the posterior wall of the left atrium. Indocyanine green dye studies done in one of the patients provided evidence that this echo-free space represents the common pulmonary venous chamber. The combination of echocardiographic evidence of RVDVO and demonstration of an echo-free space dorsal to the left atrium is strongly suggestive of TAPVC and should allow an early diagnosis in infants with this anomaly.

Recommendations for quantitation of the left ventricle by two-dimensional echocardiography. American Society of Echocardiography Committee on Standards, Subcommittee on Quantitation of Two-Dimensional Echocardiograms.

We have presented recommendations for the optimum acquisition of quantitative two-dimensional data in the current echocardiographic environment. It is likely that advances in imaging may enhance or supplement these approaches. For example, three-dimensional reconstruction methods may greatly augment the accuracy of volume determination if they become more efficient. The development of three-dimensional methods will depend in turn on vastly improved transthoracic resolution similar to that now obtainable by transesophageal echocardiography. Better resolution will also make the use of more direct methods of measuring myocardial mass practical. For example, if the epicardium were well resolved in the long-axis apical views, the myocardial shell volume could be measured directly by the biplane method of discs rather than extrapolating myocardial thickness from a single short-axis view. At present, it is our opinion that current technology justifies the clinical use of the quantitative two-dimensional methods described in this article. When technically feasible, and if resources permit, we recommend the routine reporting of left ventricular ejection fraction, diastolic volume, mass, and wall motion score.
