HYPOTHESIS The diagnostic yield of chest radiography; computed tomography (CT) of the chest, abdomen, and pelvis; and CT or magnetic resonance imaging of the brain in the initial evaluation of melanoma with metastasis to sentinel lymph nodes may not identify systemic disease. DESIGN Retrospective analysis. SETTING Tertiary care referral center. PATIENTS Of 1183 patients identified from a ...

A 73-year-old man presented with bilateral shoulder discomfort. Although the onset of his discomfort seemed to be associated with exertion, there was no chest pain. A month later, a stress test reproduced the shoulder discomfort but again without chest pain. Angiography showed significant coronary artery disease, so the patient was booked for coronary artery bypass grafting 2 months later. Rout...

A 70-yr-old woman complained of left sided chest pain and non-bilious vomiting for four days after taking a gastric bloating agent for an upper gastrointestinal study. The chest radiography revealed gastric air-fluid levels and bowel loops in the left thoracic cavity. An emergency thoracotomy was performed. The abdominal organs (stomach, spleen, splenic flexure of the colon) were in the left th...

Infection continues to be a leading cause of morbidity and mortality in patients with neoplastic disorders who are treated with myelosuppressive chemotherapy.1 In a granulocytopenic patient, fever may be the first and only sign of infection.2 Other clinical signs and symptoms that often indicate an infectious process may be blunted or missing in the presence of neutropenia. Thus, treating all f...

Chest radiography for detection of lung nodules can benefit from enhancement of suspicious structures in the lung-in many cases, these are regions containing a spherical structure and appear as a dot. In order to visualize such areas in chest radiography more clearly, and to better determine the extent of that region, in this paper, an improved Laplacian of Gaussian (LoG) filter based method fo...

Lung cancer is the leading cause of death worldwide. Screening for lung cancer may improve the poor prognosis by detecting the cancer at an early stage where radical surgery still is possible. Several randomised clinical trials using low-dose computed tomography (CT) have been launched in high-risk smokers or former smokers in the USA and Europe [1–3]. The National Lung Screening Trial (NLST) r...

PURPOSE Chest radiography is often performed on patients hospitalized with typical clinical manifestations of bronchiolitis. We aimed to determine the proportion of subjects with pathologic chest radiographic findings and the clinical predictors associated with pathologic chest radiographic findings in young children admitted with the typical presentation of bronchiolitis. METHODS We obtained...

Malignant chest wall tumors are classified into eight main diagnostic categories: muscular, vascular, fibrous and fibrohistiocytic, peripheral nerve, osseous and cartilaginous, adipose, hematologic, and cutaneous. However, there are malignant tumors that arise in the chest wall and that do not fit well in any of these categories (eg, Ewing sarcoma and synovial sarcoma). Malignant chest wall tum...
