【 摘 要 】

BACKGROUND: We compare neuropathological abnormalities in children and adults after bone marrow transplantation (BMT) by means of autopsy in the Department of Medical Pathology, Universidade Federal do Paraná (UFPR), Brazil. METHODS: Autopsy reports of 180 patients were reviewed. They were divided in two groups: patients under 15 years old and those 15 or older. Age, gender, clinical diagnosis at time of BMT, survival time, neuropathological abnormalities and cause of death were analyzed. RESULTS: In children (26.6% of total) and in the adult group (73.4% of total), the main clinical diagnoses prior to BMT were, respectively, severe aplastic anemia (31.2%) and chronic myeloid leukemia (36.3%). The mean survival time for children was 102.6 days and for adults, 185.9 days after BMT. Brain lesions were considered cause of death in 20.8% of pediatric cases and 11.3% of the adult group. Neuropathological abnormalities were morphologically similar in children and adults, with the following respectively prevalence: cerebrovascular diseases in 58.3 and 56% (p = 0.8655), neurotoxoplasmosis in 6.2% and 3% (p = 0.3856) and infections in 27 and 25.7% (p = 0.8489). CONCLUSIONS: The pediatric patients had shorter survival than adults, with increasing prevalence of neurotoxoplasmosis, and brain lesions were considered cause of death in twice as many as compared to adult patients.
