Common clinical manifestations of aspergillosis in renal transplant recipients are fever and pulmonary infiltrates, but involvement of the reproductive system is rare. We report a case of pelvic aspergillosis with tubo-ovarian abscess in a renal transplant patient. The patient received a cadaveric renal transplantation, and two episodes of acute rejection were treated with methylprednisolone pulse therapy. Surgical biopsy specimens of pelvic abscess detected by ultrasonogram and CT revealed Aspergillus. With amphotericin B treatment, the patient is well with normalization of erythrocyte sedimentation rate and C-reactive protein.
