RATIONALE: Lymph node is a preferred site for extrapulmonary tuberculosis (TB). In the thorax, mediastinal tuberculous lymph nodes can erode adjacent structures such as heart, aorta, and esophagus, forming fistula, and causing fatal consequences. However, tuberculous bronchonodal fistula as a complication of lymph node TB in adults is rarely known in terms of imaging or clinical findings. Here, a case of isolated tuberculous bronchonodal fistula appearing as the first presentation of TB in a 74-year-old male with systemic lupus erythematosus (SLE) is reported...

Inflammation, microvascular and macrovascular ischemia, valvular disease, and fibrosis are the main causes of cardiovascular disease (CVD) in autoimmune rheumatic diseases (ARDs). The silent presentation and the high mortality and/or morbidity of CVD in ARDs necessitate a reliable tool for early diagnosis. Noninvasive cardiovascular imaging, including echocardiography, nuclear imaging, cardiovascular computed tomography (CT), cardiac magnetic resonance (CMR), and hybrid imaging modalities, constitutes the main tool for monitoring of CVD in ARDs...

OBJECTIVES: In emphysema, air can flow preferentially via collateral pathways, which can connect an entire lung when incomplete fissures are present. Spiracles are openings through the chest wall into the lung parenchyma. We previously observed increased alveolar ventilation (VA) in subjects with severe emphysema, when spiracles occurred during lung transplant operations. In this study, we set out to identify a computed tomography (CT) imaging phenotype associated with improved VA via spiracles in severe emphysema...

Multiple myeloma (MM) and osteosarcoma (OS) are two common bone malignancies, however, the simultaneous occurrence of both primary bone tumors in the same patient has not been reported in the United States to date. We present a unique case in which both malignancies present concurrently in a 72-year-old man. Results of spinal magnetic resonance imaging (MRI), radiographic skeletal survey, and hematological workup established the initial diagnosis of MM. Approximately three months later, the patient was admitted with severe right hip pain and shortness of breath and was evaluated with computed tomography (CT) of the right hip, abdomen, pelvis, and chest, revealing an osseous mass with a "sunburst" pattern in the right hip, and several calcified nodules in the lungs...

Pulmonary cryptococcosis is most commonly reported in immunocompromised patients, whereas immunocompetent hosts are rarely affected and may be asymptomatic, resulting in reduced diagnostic performance of computed tomography (CT) imaging. Thus, the aim of the present study was to review the plain and contrast-enhanced chest CT scan findings of primary pulmonary cryptococcosis in immunocompetent patients, with the aim of improving the diagnosis of this type of pulmonary disease. In the present study, a total of 27 immunocompetent patients of clinically confirmed pulmonary cryptococcosis were analyzed retrospectively...

BACKGROUND: Virtual autopsies by computer tomography (CT) or magnetic resonance imaging can be valuable in cases of unexplained infant death. The radiologist must be familiar with the normal appearance of all the segments of the thoracic aorta in normal and deceased children. A thorough review of the literature revealed no prior articles describing CT changes in the ascending aorta or the aortic arch in pediatric virtual autopsies. OBJECTIVES: To compare the CT appearance of the thoracic aorta in deceased children and in those younger than 3 years of age...
