A Case of Refractory Pulmonary Coccidioidomycosis Successfully Treated with Posaconazole Therapy.

Coccidioidomycosis is an endemic fungal infection caused by the inhalation of the spores of Coccidioides species. Patients with underlying immunosuppressive illness can contract chronic or disseminated disease which requires prolonged systemic therapy. Pulmonary coccidioidomycosis remains as an illusory and abstruse disease, with increased prevalence that poses as a challenge for clinicians in developing an effective strategy for treatment. Here, we report successful treatment of a refractory case of chronic relapsing pulmonary coccidioidomycosis in a 50-year old woman with a thin-walled cavitary lung lesion who was ultimately treated with posaconazole.
