Potential nosocomial disseminated infection due to Nocardia asteroides after a prosthesis insertion in an immunocompetent patient

Nocardia infections are rare and usually occurred in immunocompromised patients with systemic dissemination from a lung infection. We report a case of an immunocompetent patient in whom Nocardia asteroides had cause psoas and cerebral abcess without pulmonary infection, a short period after a hip prosthesis insertion. The clinical history is highly suggestive of a hospital-acquired infection.
