Successful management of Histoplasma capsulatum infection of an abdominal aortic aneurysm.

A 65-year-old woman with disseminated histoplasmosis underwent resection of an atherosclerotic abdominal aortic aneurysm. Yeast forms of Histoplasma capsulatum were present in the aneurysm. Surgical resection and revascularization with a Dacron graft followed by systemic amphotericin B therapy and chronic ketoconazole suppressive therapy have resulted in a patient without symptoms 15 months postoperatively. It is important to be aware of the potential for artherosclerotic aortic aneurysm involvement by H. capsulatum.
