Scanty irregular opacities are not uncommonly observed on the chest roentgenogram in the absence of interstitial fibrosis of the lungs. In such circumstances the irregular opacities, when present, tend to be relatively scanty and seldom, if ever, exceed an ILO category of 1/1. They are found in association with cigarette smoking, especially when emphysema is also present. The development of irr...

A 37-year-old woman had pleuritic chest pain, dyspnea, and normal findings on chest roentgenogram. Lung scan showed markedly diminished perfusion to the right lung with a matched ventilatory defect. Further evaluation revealed a bronchogenic cyst. After resection, the lung scan was normal. To our knowledge, this is the first report of a bronchogenic cyst causing a reversible, unilateral ventila...

Aneurysms of the ascending aorta usually present to the right of the spine. Four patients with aneurysms of the ascending aorta or transverse arch presented to the left of the spine on the posteroanterior chest roentgenogram. On the lateral chest x-ray film, these were associated with the ascending aorta, and the apparent discrepancy led to diagnostic difficulty. All cases were proven by aortog...

A previously healthy woman aged 53 years presented with cough, night sweats and weakness. Chest roentgenogram revealed a reticulonodular infiltrate of the right upper lung. Multiple sputum cultures were positive for Mycobacterium avium-intracellulare, with no immunodeficiency disease. Fibreoptic endoscopy showed multiple tracheal cartilaginous knobs from a tracheobronchopathia osteochondroplast...

A 23 year old Algerian male was admitted to hospital due to intermittent mucopurulent and blood-stained sputum of 2 yrs duration. Temperature, blood pressure, cardiorespiratory and abdominal examination were normal. Laboratory findings showed 480 eosinophils·ml-1 in peripheral blood. The lateral and posteroanterior (PA) chest roentgenograms are shown in figures 1 and 2. Empirical treatment with...

INTRODUCTION Chronic necrotizing pulmonary aspergillosis usually occurs in mildly immune-compromised hosts or those with underlying pulmonary disease. The radiographic pattern of chronic necrotizing pulmonary aspergillosis is typically a progressive upper lobe cavitary infiltrate with pleural thickening. We report here an atypical case of chronic necrotizing pulmonary aspergillosis mimicking lu...

A4 62-year-old man was admitted with a four-week history of fever following an aorto-coronary bypass graft. The postoperative chest roentgenogram was normal. His past history included hypertension of 13 years' duration and coronary artery disease commencing three years previously. On examination, his tern-perature ranged between 37.5#{176} and 38.8#{176}C, a grade 2/6 apical systolic murmur was...

A 35-year-old woman was admitted to our hospital with an abnormal shadow on her chest roentgenogram. Computed tomography showed that a tumor was located in the right upper mediastinum. Resection of the tumor by video-assisted thoracoscopic surgery was performed. Operative findings determined that the tumor originated from the right vagus nerve and was diagnosed as schwannoma by pathological exa...
