A real mycotic aneurysm-mycotic aneurysm of the abdominal aorta due to fungal infection.

A 53-year-old male who was being followed up by a nephrology department because of type V crescentic glomerulonephritis was admitted with abdominal pain to our clinic. He was diagnosed with abdominal aortic aneurysm after the examinations. Aortic repair with a tubular graft was performed. Pathological examination of the aneurysm tissue showed fungal hyphae. We started antifungal chemotherapy with amphotericin B. A separation of the graft body occurred, and the patient was reoperated on. An excision of the graft, ligation of the aorta, and axillobifemoral graft by-pass was performed. At the 15(th) month of his discharge, the patient was readmitted to the emergency room of our clinic suffering from hematemesis. According to the examinations, an aortoduodenal fistula was diagnosed, and we performed a partial duodenal resection and end-to-end duodenoduodenostomy. We want to share this unusual, interesting, and complicated case, operated on several times because of a mycotic aneurysm due to a fungal infection.
