Xiao M, Banu A, Zeng X, Shi S, Chen S, Ge N, Tang C, Huang Y, Wang G, Hu X, Cui X, Yin F, Peng R, Chang M. Early diagnosis of Legionnaires’ pneumonia in an immunocompromised neuroblastoma patient using metagenomic next-generation sequencing: A case report. Int J Case Rep Images 2024;15(2):89–95.ABSTRACT
Introduction: Legionella pneumophila (L. pneumophila) is an aerobic, Gram-negative intracellular pathogen commonly responsible for community-acquired pneumonia and a significant causative agent in hospital-acquired pneumonia. Immunocompromised individuals, such as those undergoing organ transplantation, chemotherapy, or corticosteroid therapy, are particularly vulnerable to L. pneumophila infections. These infections often lead to Legionnaires’ pneumonia, which is challenging to differentiate from other respiratory pathogen infections based solely on clinical presentation. Moreover, traditional pathogen detection methods have low sensitivity for Legionella, further complicating the diagnosis of Legionnaires’ pneumonia.
Case Report: This case report presents a 6-year-and-9-month-old boy who developed persistent high fever during chemotherapy following the surgical resection of a retroperitoneal neuroblastoma. Imaging studies revealed significant pneumonia manifestations. Metagenomic next-generation sequencing (mNGS) of nasopharyngeal swabs and bronchoalveolar lavage fluid confirmed the diagnosis of Legionnaires’ pneumonia.
Conclusion: This case highlights the challenges and critical importance of early and accurate diagnosis of Legionella infections, particularly in immunocompromised patients such as those undergoing chemotherapy. The use of advanced diagnostic techniques like metagenomic next-generation sequencing (mNGS) is essential for the prompt identification and treatment of Legionnaires’ pneumonia in this vulnerable population, improving patient outcomes. This report emphasizes the need for heightened awareness and advanced diagnostic techniques in managing atypical pneumonia pathogens in vulnerable populations.
