He presented with low grade fever, dyspnoea and right-sided thoracic pain and was admitted due to a treatment-refractory infection. After a prolonged period of symptoms and diagnostics, acid-fast bacilli were demonstrated in pleural fluid and PCR revealed <jats:italic>M. genavense<\/jats:italic>. The patient was treated with intravenous amikacin, peroral azithromycin, rifampicin and ethambutol for a total of 18 months, with a good clinical and radiological treatment response. Infection with <jats:italic>M. genavense<\/jats:italic> is rare in HIV-negative immunocompromised hosts. Diagnosing and treating mycobacterial infections, especially for more rare species, remains a challenge as clinical evidence is sparse. Nonetheless, the disease-causing infection must be considered in symptomatic and immunocompromised patients.<\/jats:p>","DOI":"10.1136\/bcr-2023-254792","type":"journal-article","created":{"date-parts":[[2023,5,5]],"date-time":"2023-05-05T10:16:19Z","timestamp":1683281779000},"page":"e254792","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Disseminated
