Although ceftriaxone has been shown to be active in vitro,3 its clinical efficacy has been demonstrated only in isolated cases.4 A clear clinical and radiologic initial response was obtained in the present case, which was maintained over time. Other studies on the clinical utility of ceftriaxone in cases of Nocardia infection should be carried out.
