Management of Opportunistic Infections after Organ Transplantation
김임경,주만기 대한이식학회 2015 Korean Journal of Transplantation Vol.29 No.1
Solid organ transplantation is a therapeutic option for end-stage organ diseases. However, complications including infection and graft rejection, which are related to immunosuppressive therapy, remain the major causes of morbidity and mortality following solid organ transplantation. The optimal approach to infection in solid organ transplant recipients is prevention; failing this, prompt and aggressive diagnosis and therapy are essential. In addition, the epidemiology of infections after solid organ transplantation has shifted as a result of changes in immunosuppressive strategies and improved survival. Immunosuppression must be linked with appropriate vaccinations, donor and recipient screening, patient education regarding infectious risks and lifestyle, monitoring, and antimicrobial prophylaxis.

We report on a case of hepatic splenosis. A 32-yr-old man underwent a splenectomy due to trauma at the age of 6. He had been diagnosed as being a chronic hepatitis B-virus carrier 16 yr prior to the surgery. The dynamic computer tomography (CT) performed due to elevated serum alpha-fetoprotein (128 ng/mL) demonstrated two hepatic nodules, which were located near the liver capsule. A nodule in Segment IVa had a slight enhancement during both the arterial and portal phases, and another nodule in Segment VI showed a slight enhancement only in the portal phases. Dynamic magnetic resonance imaging (MRI) of the mass in Segment VI showed enhanced development in the arterial phases and slight hyperintensivity to the liver parenchyma in the portal phases. These imaging findings suggested a hypervascular tumor in the liver, which could be either focal nodular hyperplasia, adenoma, or hepatocellular carcinoma (HCC). Even though these lesions were diagnosed as HCC, some of the findings were not compatible with typical HCC. On dynamic CT and MRI, all lesions showed a slight arterial enhancement and did not show early venous washout. All lesions were located near the liver capsule. These findings, along with a history of splenectomy, suggested a diagnosis of hepatic splenosis.
