We present a case of 45-year-old female patient with the diagnosis of seropositive rheumatoid arthritis, who was admitted to our rheumatology department with exacerbation of the disease. The patient's disease activity score (DAS 28) was 6.9. Physical examination revealed changes in the lung auscultation as a rough breathing sound at the middle and lower lobe of the right lung. Chest X-ray revea...

INTRODUCTION Pulmonary amyloidosis is an uncommon disease, characterized by extracellular deposition of fibrillary protein in the lungs. It appears in three forms: tracheobronchial, nodular pulmonary, and alveolar septal. There are few reports of long-term observation of primary pulmonary amyloidosis. CASE PRESENTATION We present the case of a 47-year-old man who presented with fever, dyspnea...

New opportunities for research in computer aided diagnosis (CAD) of pulmonary nodules resulted from the emergence of publicly available clinical case studies, containing expert radiologist-defined truth. Access to high-quality labeled data affords non-clinical image analysis groups the opportunity to pursue diagnostic imaging research. Historically, clinical research centers reported results ba...

A deep learning algorithm, developed for malignancy risk estimation of pulmonary nodules detected at screening CT, demonstrated good discriminative performance in a large independent validation set.

A 35 year old Caucasian female housekeeper was admitted to our hospital on October 2, 1985 for investigation of pulmonary nodules discovered three weeks previously on a routine chest radiogram. Careful examination of the X-ray revealed four nodules of about 8 mm in diameter scattered in the middle and lower part of the left lung and in the middle and upper lobes of the right lung (fig. 1). The ...

Syphilis is a sexually transmitted disease caused by Treponema pallidum. The prevalence of this disease has recently increased worldwide. However, pulmonary involvement in secondary syphilis is extremely rare. A 51-year-old heterosexual male patient presented with multiple pulmonary nodules with reactive serology from the Venereal Disease Research Laboratory test and positive fluorescent trepon...

STUDY OBJECTIVES To determine the etiology and the clinical and radiographic predictors of the etiology of pulmonary nodules in a group of HIV-infected patients. DESIGN Retrospective analysis. SETTING A large urban hospital in San Francisco, CA. PATIENTS HIV-infected patients evaluated at San Francisco General Hospital from June 1, 1993, through December 31, 1997, having one or more pulmo...

OBJECTIVES To describe the unusual immunohistological characteristics of two pulmonary rheumatoid nodules showing ectopic lymphoid follicles and the features normally associated with rheumatoid synovial membrane, and to discuss the implications of this novel observation. METHODS Two formalin-fixed wax-embedded pulmonary rheumatoid nodules were processed for immunohistology. RESULTS The cent...
