[Pseudo-aneurysm of the left ventricle. Non-invasive diagnosis of 2 cases].

Left ventricular pseudoaneurysm is a rare condition which may develop after rupture of the ventricular myocardial wall. A localized hemopericardium confined is then formed outlined by the parietal pericardium. The pseudoaneurysmal sac is formed by clots and fibrous pericardial tissue and is directly connected to the ventricular chamber. There are no specific clinical signs to identify the disease. Two dimensional echocardiography and computerized tomography can allow the correct diagnosis to be made before cardiac catheterization. Two cases of left ventricular pseudoaneurysm occurring one after chest trauma and the other after acute myocardial infarction are reported.

[Computerized tomography in the study of malignant tumors of the larynx].

A systematic investigation was carried out on 93 patients suffering from laryngeal tumours who underwent computed tomography and xeroradiography. A comparison is made between CT, xerographic, clinical and endoscopic findings. The value is stressed of functional informations obtained from CT performed during quiet breathing and phonation. The outstanding value of CT is the accuracy in definition of tumor extension and involvement of the laryngeal and paralaryngeal tissues. CT can be useful in diagnosis of regional lymph nodes metastases. The correct evaluation of the tumour is greatly helpful in surgical treatment and radiotherapy planning.

[X-ray computed tomography in non-neoplastic pathology of the larynx].

The authors describe the CT findings in 57 patients suffering from various non-neoplastic disease of the larynx: chronic laryngitis, pseudotumor, paralysis, post-traumatic lesions, laryngocele, cyst. CT is usefull in evaluating site and extension of the disease, as well as its relations with the surrounding tissues. The densitometric evaluation and the functional tests are important in differential diagnosis with malignant neoplasms.

[Computerized tomography in studies of the larynx. Normal anatomy].

The CT picture of the normal larynx was studied in 15 volunteers free from laryngeal disorders and in 142 patients examined at the level of the neck for a variety of pathological conditions. The investigation was carried out during normal breathing and during phonation. The diagnostic importance of these two functional attitudes is stressed. Tomographic anatomy was described according to axial planes: suprahyoid, hyoid, subhyoid, supraglottic, glottic and subglottic. In addition to the laryngeal structure, the cartilaginous skeleton and the anatomical formations surrounding the larynx were also investigated. CT was found to be a very useful and accurate tool for studying the delicate structures which form the larynx.

[Coronary artery spasm induced by the somministration of ergonovine maleate in subjects with spontaneous angina (author's transl)].

In 6 patients affected by spontaneous angina with S-T elevation and coronariographic findings of obstruction, intravenous administration of ergonovine maleate determined the same clinical and ECG patterns of spontaneous episodes. The coronary arteriography during pain showed a marked spasm with occlusion of a large coronary vessel in four patients. In 2 patients with atypical chest pain and normal coronariogram, E.M. did not induce pain, ECG abnormality or coronariographic alterations. The role of spasm in spontaneous angina is discussed.
