| 1 | Renal aspergillosis in a liver transplant patient: A case report and review of literature显示文摘BACKGROUND Aspergillosis is a frequent invasive fungal infection in liver recipients(affecting 1%-9.2% of all patients), second only to candidiasis. Significant risk factors for invasive aspergillosis in liver recipients include corticosteroid therapy, neutropenia, T-cell dysfunction, renal failure and requirement for renal replacement therapy. Aspergillus infection usually affects the lungs of liver recipients, with hematogenous dissemination occurring in 50%-60% of cases. Renal involvement is rare and is considered to occur in 0.4% of all cases of invasive aspergillosis.CASE SUMMARY This paper describes a case of a liver recipient presenting with a newly formed renal mass a year after liver transplantation. The patient underwent liver transplantation due to alcoholic liver cirrhosis, with preoperative corticosteroid therapy and postoperative immunosuppressants(tacrolimus and mycophenolate mofetil). His 1-year follow-up was uneventful, with a satisfying graft function and lack of any symptoms. During a routine follow-up abdominal ultrasound, he was diagnosed with a renal tumor. The renal ima-ging findings were inconclusive(with a differential diagnosis to renal cell carcinoma), while the computed tomography(CT) of the chest showed scar tissue in the lungs suggestive of previous inflammation. The patient underwent radical nephrectomy, with histopathological analysis showing renal aspergilloma, yielding postoperative treatment with voriconazole. His follow up was uneventful, and the chest CT did not show any change in pulmonary lesions. This case illustrates the possibility of aspergillosis affecting the lungs of liver recipients, subsequently affecting the kidney and forming an aspergilloma.CONCLUSION Clinicians should be aware of aspergilloma mimicking solid organ tumors in organ recipients. | Brigita Smolovic Batric Vukcevic Damir Muhovic Marina Ratkovic | 2018 | World Journal of Clinical Cases2018，6，16： | 2 |
