BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2012-006867 DESCRIPTION A young woman presented with three pulmonary nodules identified in the right lower lobe discovered on an outside CT scan of the abdomen which was performed to investigate right flank pain. The pain was ascribed to urinary tract infection and resolve...

In order to improve the detection accuracy of pulmonary nodules in CT image, considering two problems of pulmonary nodules detection model, including unreasonable feature structure and nontightness of feature representation, a pulmonary nodules detection algorithm is proposed based on SVM and CT image feature-level fusion with rough sets. Firstly, CT images of pulmonary nodule are analyzed, and...

The accurate segmentation of pulmonary nodules is an important preprocessing step in computer-aided diagnoses of lung cancers. However, the existing segmentation methods may cause the problem of edge leakage and cannot segment juxta-vascular pulmonary nodules accurately. To address this problem, a novel automatic segmentation method based on an LBF active contour model with information entropy ...

BACKGROUND The aims of the study were to determine the accuracy of fluorodeoxyglucose positron emission tomography (FDG-PET) in detecting pulmonary metastasis through video-assisted thoracoscopic surgery (VATS), a technique that allows the excisional biopsy of small pulmonary nodules in patients with known malignancies. MATERIALS AND METHODS Between October 2007 and April 2010, 28 patients wi...

OBJECTIVE Pulmonary metastasectomy is beneficial in select patients. The sensitivity of (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) for pulmonary metastasis is unknown. The aims of the study were to determine the accuracy of FDG-PET in detecting pulmonary metastasis and identify factors affecting sensitivity. METHODS All patients undergoing metastasectomy from September 20...

BACKGROUND Pulmonary histoplasmosis is a mycotic infection that often resembles pulmonary malignancy and continues to complicate the evaluation of pulmonary nodules. CASE PRESENTATION We report a case of an immunocompetent patient who, despite adequate treatment for known histoplasmosis lung infection, presented with radiological and F-18 fluorodeoxyglucose (FDG) positron emission tomography ...

Sarcoidosis is a multi-system inflammatory disorder of unknown etiology that is manifested by the presence of non-caseating granulomas. Multiple pulmonary nodules are rare presentations of sarcoidosis. We report a case of nodular sarcoidosis in a young male of Middle-East origin who had initially presented with bilateral painful ankle edema. His chest X-ray showed multiple bilateral pulmonary n...

We report the case of a 69-year-old man with acute pulmonary echinococcosis. A computed tomographic scan of the thorax revealed the presence of multiple nodules in both lungs, and laboratory tests showed eosinophilia and the presence of antibodies against Echinococcus granulosus. Therapy with albendazole led to resolution of the pulmonary nodules and a normalization of the white cell count. To ...

Multiple lung cavitations and endobronchial nodules are rare presentations of newly diagnosed and recurrent Hodgkin's disease. The clinical and radiological features can be confused with pulmonary tuberculosis, which can be difficult to exclude in endemic areas. However, the presence of endobronchial nodules point, towards Hodgkin's disease. Differential diagnosis is aided by the fact that thes...
