Secondary point was to investigate the pattern and severity of PRES in children with thalassemia-THAL and sickle-cell disease-SCD after autologous hematopoietic stem cell transplantation (aHSCT). Finally, we evaluate the presence of atypical PRES presentation and the involved area of central nervous system. Two neuroradiologists analyzed retrospectively MRI of 21 transplanted children for THAL or SCD treated with CI, with neurological symptoms and signs of PRES. The Bartynski and Boardman classification has been used for PRES pattern while McKinney scale for PRES severity. Fisher Exact Probability test or Chi-square test were used to compare the categorical data. In the 21 transplanted children the PRES severity was typically mild (85.7%) without preferring radiological pattern at MRI. The analysis didn't show significant association between PRES pattern or PRES severity and previous hemoglobinopathy (THAL or SCD). No atypical PRES presentation has been found. PRES severity in transplanted children for hemoglobinopathy is typically mild. Notwithstanding children affect...
