A 44-year-old woman was admitted to our hospital in August 1999 for multiple large nodules detected on chest roentgenogram in an annual health check. Chest CT scans showed bilateral large nodules (>10 mm in diameter) with irregular margins and multiple thin walled cystic lesions. From these radiologic examinations, we suspected pulmonary Langerhans cell histiocytosis. Histological examination o...

Solitary fibrous tumor of the pleura is a rare mesenchymal tumor, representing less than 5% of all neoplasms associated with the pleura. A 57-year-old man had general malaise without chest symptoms for 1 month. A chest roentgenogram and computed tomography showed a giant mass in the left thorax. Although the tumor compressed the descending aorta and other mediastinal structures strongly, thereb...

A 57 year old man, receiving compensation for talc pneumoconiosis since 1977, was admitted to hospital for the first time in 1987, with symptoms of weight loss, fever, dyspnoea and productive cough. A chest roentgenogram showed bilateral cavitation. Two years later, Mycobacterium xenopi was found in sputum cultures. Despite specific oral antibiotherapy, the patient's health deteriorated and he ...

A 24‐hour‐old, term neonate, weighing 3.4 kg, born by cesarean section presented with a huge sacral mass of size 20 cm × 20 cm, involving coccyx, extending to both buttocks, with intact skin [Figure 1]. Tumor resection was planned at 24 h of birth. Preoperative hemoglobin was 16 g/dl, and other investigations were within normal limits. Blood for grouping and crossmatching was sent. Chest roentg...

Case summaries of four patients with bilateral hilar lymphadenopathy (BHL) caused by metastatic renal cell carcinoma are presented, and these and eight similar cases from the literature are analyzed. In nine patients, sarcoidosis was the provisional clinical diagnosis, but four of these patients had a past history of renal cell carcinoma. In the remaining five patients, a distinction from sarco...

Introduction : The objective of this study was to give a description of the most prominent atypical radiological presentations of lung hydatidosis. Materials and methods: All patients diagnosed with pulmonary hydatidosis by surgical exploration were included in this study. Standard chest roentgenogram and computed tomography CT) were evaluated before surgery for lung cysts or unknown lesions. R...

teriovenous malformation was diagnosed 19 years earlierwhen seizures occurred. She was initially treated with carbamazepine, phenytoin, and phenobarbital. A few years later a right hemiparesis developed, which subsequently improved with treatment. One year be¬ fore admission, again a progression of the hemiparesis was noticed. Otherwise, the patient's medical history did not disclose any other ...

We report the case of a 26-year-old woman with ventricular septal defect associated with a typical coin lesion as shown on the chest roentgenogram. Selective angiography revealed the coin lesion to be caused by an aneurysm of a tertiary pulmonary arterial branch. In addition, two smaller aneurysms were noted. It is postulated on clinical and histologic grounds that the aneurysms were caused by ...

A 69-year-old woman with idiopathic thrombocytopenic purpura, who was regularly followed and treated with prednisolone and danazol, was admitted to our hospital because of shortness of breath. Chest roentgenogram showed a large amount of left-sided pleural effusion. Gram-positive branching rods, subsequently identified as Nocardia farcinica, were isolated from the fluid. Antibiotic treatment to...

Three cases of pulmonary echinococcosis in native American children emphasize the need to consider the diagnosis in the differential diagnosis of mass lesions of the chest when the appropriate environmental conditions are present. Two children presented with a non-productive cough, while one was asymptomatic. Surgery is the treatment of choice for pulmonary echinococcal cysts. All three childre...
