Neuropathologic findings after organ transplantation. An autopsy study.
Since 1972 organ transplantations of kidney, bone marrow, liver, heart and lung have been performed at the University Hospital of Essen, Germany. Out of 2535 transplantations until September 1993, autopsies were performed in 157 patients In 25 patients (15.9%) neuropathologic findings (n = 26) were found. In 97 autopsies after bone marrow transplantation, 9 patients (9.3%) exhibited a severe neuropathologic alteration. In six patients (6/9; 66.6%), necrotisizing toxoplasmose encephalitis was found. Other cases showed a septic-metastatic mycotic encephalitis with crypto-coccus neoformans and candida albicans (n = 2) and leucemia infiltrates (n = 1). Massive cerebral hemorrhage was the most frequent neuropathologic finding after liver (4/8) and kidney transplantation (3/6). In addition liver-transplanted patients exhibited septic-metastatic encephalitis (3/8) and embolic brain infarct (1/8) as well as cerebral metastases (2/6) and primary malignant cerebral lymphoma in kidney transplantation (1/6). CNS findings in five autopsies after heart-lung-transplantation were diverse. They comprised intracerebral hemorrhage, intravasal lymphoma and septic-metastatic encephalitis, respectively. In summary, neuropathologic autopsy findings after organ transplantation are diverse and preferentially comprise infections, cerebral hemorrhages, and malignant lymphomas. After bone marrow transplantation, the most frequent neuropathologic autopsy finding was toxoplasmose encephalitis and massive cerebral hemorrhages after liver and kidney transplantations.
