Nocardia cyriacigeorgica Brain and Lung Abscesses in 77-Year-Old Man With Diabetes

Cureus. 2021 Nov 8;13(11):e19373. doi: 10.7759/cureus.19373. eCollection 2021 Nov.


Nocardia species are difficult to identify, saprophytic, aerobic actinomycetes that are associated with high mortality rates and primarily affect immunocompromised hosts. Recently, the number ofdiagnoses of Nocardia cyriacigeorgica has grown in the United States, yet complicated clinical diagnosis and costly identification methods presume an underestimation of its presence in patients. We describe a case of brain abscess secondary to a pulmonary infection in an elderly, diabetic, Afghani man with an extensive history of chewing tobacco use.
