Pulmonary tuberculoma commonly causes an increase in FDG uptake. These results suggest that in geographic regions with a high prevalence of granulomatous lesions, positive FDG PET results should be interpreted with caution in differentiating benign from malignant pulmonary abnormalities.
Atelectasis caused by smooth bronchial narrowing, surrounded by calcified or noncalcified lymph nodes, in elderly and nonsmoking women is a typical finding of anthracofibrosis. Calcified lymph nodes adjacent to the involved bronchi and multifocal involvement of bronchial narrowing may be helpful in differentiating this condition from lung cancer.
Percutaneous transthoracic fine needle aspiration (PCNA) and biopsy (PCNB) are well-accepted methods for the diagnosis of various intrathoracic lesions. Implantation of cancer cells along the needle tract is one ofthe rarest complications of these techniques, but was found along the needle tract in a patient who underwent PCNB for lung cancer.
3)] were analyzed and compared. There were 21 men and 15 women ranging in age from 27 to 77 years. Distribution (even, centraL or peripheral) and patterns of pulmonary edema were compared between the three groups.Results: The distribution of edema, appearing as consolidation or ground-glass opacity, was even in 75% (n=15) of group 1, even in 46 % (n=6) and central in 38 % (n=5) ofgroup II, andperipherally predominant in 100% (n = 3) of group III. Interlobular septal thickening was seen in 80% (n = 16), 69 % (n = 9), and 0 % of group 1, II and III, respectively. Centrilobular ground-glass opacity was noted in six patients.Conclusion: In spite of various findings and considerable overlapping of the findings of pulmonary edema, the distribution and pattern of edema differed according to the cause, and this can be helpful for differential diagnosis.Index words: Thorax, CT Lung, fluidAddress reprint requests to: Jung-Gi 1m, M.D.,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
