1. [A pulsating tumor in the chest wall]

Author

R, Rienmüller, D, Hahn, and M, Manz

Subjects
Diagnosis, Differential, Mediastinal Cyst, Pericarditis, Constrictive, Drainage, Humans, Pericarditis, Tuberculous, Middle Aged, Tomography, X-Ray Computed, Abscess
Abstract

A pericardial constriction with calcification and a pulsating cyst is an unusual outcome after a pericardial windowing. The application of cardiac computed tomography evaluating the morphological parameters of the heart chambers and the adjacent vessels is an appropriate noninvasive method in the diagnostics of pericardial constriction.

2. [The diagnostic value of computerized tomography in mediastinal diseases depending on their localization]

Author

B, Sommer, J L, Doppman, W, Stelter, B, Mayr, R, Rienmüller, and J, Lissner

Subjects
Aortic Dissection, Carcinoma, Bronchogenic, Lymphoma, Thymoma, Hyperparathyroidism, Mediastinal Diseases, Humans, Aorta, Thoracic, Radiography, Thoracic, Tomography, X-Ray Computed, Mediastinal Neoplasms, Aortic Aneurysm, Neoplasm Staging
Abstract

The diagnostic ranking and importance of computerised tomography was examined in 116 patients with abnormal findings in the mediastinal region, and was compared with conventional, non-invasive x-ray examinations. This method also yielded significant CT-specific additional information in the anterior mediastinum in 74.4% of the cases, in the mesomediastinum in 69.1%, in the posterior mediastinum in 79.2% in the upper thoracic aperture in 94.4% and in the paracardial region in 100% of the cases. The hilar region is an exception; in 68.8% of the cases, both methods were rated equal, whereas in 28.1% of the cases assessment via the CT method was even inferior. The specific additional information furnished by the CT method justifies a wider application of CT in solving the following problems concerning the mediastinum. -- clarification of a suspected but not yet established space-occupying growth in the mediastinum, before using invasive diagnostic methods such as mediastinoscopy and angiography; -- staging of an already identified primary mediastinal tumor of malignant lymphoma; -- in case of suspected changes in the large mediastinal vessels before employing angiography; -- on-target in the following diseases: bronchogenic carcinoma (because of improved pretherapeutic staging according to the TNM system), myasthenia gravis and identification of thymoma, hyperparathyroidism with suspected dystopic parathyroid glands.

3. [End-diastolic volumes of the left ventricle in computer tomography in comparison to heart catheter ventriculography]

Author

R, Rienmüller, J, Lissner, A, Kment, J, Bohn, B E, Strauer, D, Hellwig, E, Erdmann, J, Cyran, G, Steinbeck, and D, Höss

Subjects
Heart Defects, Congenital, Cardiac Catheterization, Heart Diseases, Diastole, Cardiac Volume, Heart Ventricles, Hypertension, Humans, Coronary Disease, Cardiomyopathies, Tomography, X-Ray Computed
Abstract

In 47 patients the authors calculated the volume at the end of a diastole according to both the cardiac catheter ventriculogram and the CT ventriculogram, comparing the results obtained with each of these methods. A linear regression was found. The correlation coefficient was approximately r = 0,96; n = 47. Cardiological examination revealed that of the examined patients (including the cardiac catheter finding) 18 patients had coronary heart disease, whereas 9 had cardiomyopathy, 6 arterial hypertension, 9 had various cardiac abnormalities and 5 did not show any organically manifest heart disease. The article discusses CT determination of the volume at the end of the ventricular diastole, and discusses the results.
