title: Pseudoaneurysm of the iliac artery secondary to Aspergillus infection after kidney transplantation.
abstract: Infectious complications are the top causes of morbidity and mortality in patients who undergo renal transplantation. We report a patient who received a cadaveric renal transplant in Mainland China. One year post-transplantation, the patient had right buttock pain with radiation to the leg. Swelling and tenderness over the right groin was also found. Magnetic resonance imaging revealed a multilobulated cystic lesion, about 8 x 7 cm, at the right iliac fossa and presacral region extending to the posterior aspect of the graft kidney and up to the right psoas muscle. Drainage of the intra-abdominal abscess was performed. The abscess culture showed presence of Aspergillus spp. The patient had received steroids, tacrolimus and mycophenolate mofetil, which could be a risk factor for fungal infection. The cause of Aspergillus infection in our patient remains unclear. It may have been due to immune system insufficiency of the patient rendering the patient prone to infection. Pseudoaneurysm formation of the internal iliac artery following Aspergillus infection after kidney transplantation is rarely reported. Although it is a dilemma, once a severe situation such as pseudoaneurysm with aspergillosis presents, graft removal is suggested.
