Abstract
A 76-year-old woman who was being treated for Mycobacterium avium lung infection discontinued treatment after showing improvement; however, her symptoms and imaging findings worsened thereafter. A diagnosis of a relapse of the Mycobacterium avium lung infection was made and treatment was resumed. However, the symptoms did not improve, and non-Penicillium marneffei species were detected using bronchoscopy samples. A diagnosis of non-Penicillium marneffei penicilliosis was made, and treatment with itraconazole was started, which improved the patient’s condition. The findings from this case suggest that non-Penicillium marneffei penicilliosis should be considered in patients treated for infection with nontuberculous mycobacteria.
