A case of massive bilateral diaphragmatic rupture following a low impact motor vehicle accident is described. The patient experienced herniation of intraabdominal contents into the thoracic cavity, but suffered no additional injuries. Few cases of bilateral diaphragmatic rupture have been reported and no cases of acute bilateral rupture have been described as an isolated injury. Diaphragmatic r...

The differential diagnosis of masses in the posterior mediastinum includes neurogenic neoplasms, cysts, esophageal tumors, infectious processes including abscesses, and disorders of the thoracic spine. Nonoperative procedures, including transcutaneous and transbronchial biopsies and thoracoscopy, may not lead to a definitive diagnosis. We present two cases in which a neurogenic tumor, with and ...

A healthy 37 yr old female presented with recurrent right-sided chest pain which spontaneously disappeared. On a chest roentgenogram a lesion in the right cardiophrenic angle was found. Magnetic resonance imaging suggested a cystic structure. During thoracotomy a pericardial diverticulum was found. The pain was probably caused by intermittent volvulus of the diverticulum.

Proximal pulmonary artery aneurysms (PAAs) are rare. Most are associated with secondary pulmonary hypertension or a variety of rare systemic disorders. An asymptomatic adult patient presented with bilateral hilar enlargement on a routine chest roentgenogram. Computed tomography of the chest revealed 5 cm bilateral proximal PAAs with a normal pulmonary trunk. The clinician should consider proxim...

The introduction of new ideas and concepts that lead to change in practice has always caused some degree of controversy, especially in medicine. At first glance, the concept of noninvasive imaging for calcium as a screen to identify patients at high risk for future coronary events would seem the most intense; however, one must only reflect on past controversies to gain an appropriate perspectiv...

A pseudolesion encountered in the lateral chest roentgenogram of normal patients is described. This concatenation of shadows can produce an opacity which projects over the distal aortic arch and can simulate a mass or pneumonia. This pseudolesion can be found in 4 to 5 percent of normal lateral chest films and is formed by superimposition of normal upper lobe vascular structures.

A 64-year-old woman was referred to the Kaohsiung Medical University Hospital for evaluation of a mass adjoining the left cardiac border, identified on a chest roentgenogram (Figure 1, A). She had no history of Kawasaki’s disease, chest trauma, or pulmonary problems, except a recent cough with whitish sputum. A grade 2 continuous murmur could be heard at the left upper sternal border. Enhanced ...

Analysis was made of 20 patients with endobronchial tuberculosis proven by fiberoptic bronchoscopy and bronchial biopsy. Unlike prechemotherapy reports, the disease affects the older age group and more men. Only one half of the patients had fever, and the characteristic localized wheeze was found in 15 percent of cases. Chest roentgenogram showed typical collapse-consolidation in most cases; ho...

Here we describe a case of a secondary bronchiolitis obliterans organizing pneumonia (BOOP), which was associated with repeated respiratory infections caused by carbamazepine (CBZ)- induced hypogammaglobulinaemia. A 49-year-old woman had been treated with CBZ (400 mg/day). Two and a half years later, she developed of dyspnea with productive cough and high-grade fever. Chest roentgenogram and co...
