Pulmonary adenofibroma is a rare tumor, with a few reported cases in the literature. Radiologically, the lesion appears as a solitary pulmonary nodule in most cases, and the multiplicity of this disease entity is extremely rare. We present an unusual case of pulmonary adenofibroma in a 71-year-old woman manifested as two nodules in different lobes of the lung on CT.

It can be diagnosed by gaining tissues in lung parenchyma or detecting antigen in blood or bronchoalveolar lavage fluid. Here we report an immunocompetent 32-year-old male patient with diabetes mellitus diagnosed with cryptococcal pneumonia after a ultrasound-guided percutaneous supraclavicular lymph node core needle biopsy.

Materials And Methods: We enrolled 43 patients for whom XR, PNS DT, and OMU CT were performed. We measured effective doses (EDs) of XR, DT, and OMU CT using Monte Carlo simulation software.
Thoracic lymphomas most frequently involve mediastinal lymph nodes in the anterior mediastinum and paratracheal areas. The lymphomas may also involve lung, thymus, pleura, pericardium, chest wall, and the breast and their radiologic manifestations are diverse. Lymphomas (mostly BALT lymphoma and large B-cell lymphoma) may arise primarily from the lung with various imaging features including single or multiple nodule(s) and area(s) of consolidation.

There are few reports that have described a relationship between tumor recurrence and variable factors such as stage, pathology, surgical method, and mode of recurrence.
Purpose: To determine factors associated with tumor recurrence after resection of lung cancer.
Introduction: Limited data are available regarding the diagnostic and prognostic utility of brain natriuretic peptide (BNP) in patients with chronic kidney disease (CKD) in the intensive care unit (ICU) setting.
Methods: All patients with CKD and a serum creatinine (Cr) of 2.0 mg/dl or higher admitted to the ICU between January 2006 and September 2007 were enrolled in this study.
Matrix metalloproteinase-9 (MMP-9) may play an important role in emphysematous change in chronic obstructive pulmonary disease (COPD), one of the leading causes of mortality and morbidity worldwide. We previously reported that simvastatin, an inhibitor of HMG-CoA reductase, attenuates emphysematous change and MMP-9 induction in the lungs of rats exposed to cigarette smoke. However, it remained uncertain how cigarette smoke induced MMP-9 and how simvastatin inhibited cigarette smoke-induced MMP-9 expression in alveolar macrophages (AMs), a major source of MMP-9 in the lungs of COPD patients.

Materials And Methods: Six hundred and fifteen cases of PCNAB (591 initial PCNAB and 24 repeat PCNAB) performed under the CT or fluoroscopy guidance in 591 patients was enrolled. The procedure was done using an automated biopsy gun with a 20-G needle (519 cases) or a 20-G aspiration needle (96 cases).
Purpose: To evaluate the utility of clinical, thin-section computed tomography (CT), and histopathologic findings in predicting the prognosis of patients with usual interstitial pneumonia (UIP) or fibrotic nonspecific interstitial pneumonia (NSIP).
Materials And Methods: The institutional review board approved this retrospective study, with waiver of informed consent. Included were 108 patients (71 men, 37 women; mean age, 61 years +/- 8 [standard deviation]) with UIP (n = 79; 60 men, 19 women; mean age, 63 years +/- 7.
In patients who have lymphoma, the presence and distribution of thoracic involvement is important in both tumor staging and treatment. Thoracic involvement in Hodgkin lymphoma (HL) is more common than in non-Hodgkin lymphoma (NHL). In HL, mediastinal lymphadenopathy with contiguous spread is a hallmark, and lung parenchymal involvement at the initial presentation is almost always associated with mediastinal lymphadenopathy.

Our institutional review board approved this retrospective study with a waiver of informed consent. We selected 100 patients (M:F=56:44, mean age; 58 years) with a pathologically proven solid or partly solid SPN.

Methods: We retrospectively evaluated ultrasound images and medical records of 263 breast masses from 199 patients that were removed with an ultrasound-guided vacuum-assisted device. All lesions were assumed as benign on ultrasound imaging or had been confirmed as benign by a previous core needle biopsy.
Background: Few articles have been published on imaging findings of marginal zone B-cell lymphoma of bronchus-associated lymphoid tissue (BALT) of the lung. We present CT scan and 18F-fluorodeoxyglucose (FDG) PET scan findings of the disease.
Methods: From March 1995 to February 2007, 21 pretreatment patients (male patients, 9; female patients, 12; age range, 35 to 76 years; mean [+/- SD] age, 54 +/- 10.
