High-throughput sequencing of bronchoalveolar lavage fluid confirms pulmonary paragonimiasis: A case report.

ABSTRACT:

Paragonimiasis, a rare parasitic disease, often presents diagnostic challenges due to its insidious onset, multiorgan involvement, and nonspecific clinical manifestations, frequently leading to misdiagnosis.

A 45-year-old male was hospitalized 5 times across 4 tertiary centers in Guilin (January 2023-October 2024) for recurrent cough, hemoptysis, and persistent eosinophilia (lasting 2 years). Initial leukocytosis normalized,
