Identification of in bronchoalveolar lavage fluid and peripheral blood using next-generation sequencing in a patient with septic shock: a case report and literature review.

We present a case report of a 59-year-old male diagnosed with pancreatic cancer with multiple abdominal metastases, in whom metagenomic next-generation sequencing unexpectedly identified genomic sequences in both bronchoalveolar lavage fluid and peripheral blood specimens. Subsequent examination further confirmed the presence of viable eggs in the stool samples. The findings underscore the prognostic significance of enhanced diagnostic protocols for parasitic infections in oncological cases. This investigation demonstrates the clinical utility of molecular diagnostic approaches and alternative biological specimens for detecting infection.
