Hemoptysis and High-Density Shadow of Both Lungs Combined with Elevated Serum G-Lipopolysaccharide Misdiagnosed as Bronchiectasis with Gram-Negative Bacterium Infection Ultimately Confirmed as Mycobacterium Iranicum Infection by CT-guided Percutaneous Lung Biopsy and Next Generation Sequencing (NGS): a Case Report and Literature Review |
Background: G-lipopolysaccharide, a component of the cell wall of Gram-negative bacteria, is called lipopolysaccharide. The detection of G-lipopolysaccharide can be used for the early diagnosis of infectious diseases, but some-times G-lipopolysaccharide provides limited help. We report a case of a patient with hemoptysis and high-density shadow of both lungs combined with elevated serum G-lipopolysaccharide which mimicked bronchiectasis with Gram-negative bacterium infection. It was ultimately confirmed as Mycobacterium iranicum infection by CT-guided percutaneous lung biopsy and next generation sequencing.
