Abstract:
Objective To improve recognition of posterior reversible encephalopathy syndrome (PRES) in children. Methods Two children with PRES admitted to children's hospital were included. Clinical data were retrospectively studied and related literatures were reviewed. Results The primary diseases of the two patients are systemic lupus erythematosus and nephritic syndrome, respectively. They all developed an acute onset of headache, visual changes, consciousness disturbance, hypertension and seizures. Cranial MRI showed bilateral parietal, temporal and occipital cortical or subcortical lesions with hypointensity on Tl-weighted imaging and hyperintensity on T2-weighted imaging. Clinical symptoms resolved soon and radiographic recovery occurred within 14 to 21 days with prompt anti-hypertension treatment and supportive care. Among the mechanisms which might contribute to the development of PRES, acute elevated blood pressure seems to be the most important factors in these two cases. Prompt anti-hypertension treatment usually can reverse the PRES lesion. Conclusions It is important to improve cognition of PRES in children. Delayed treatment can cause permanent neurological impairment. Doctors should be alert to this syndrome. Early diagnosis and prompt treatment are very important. (J Clin Pediatr,2010,28(2):168-170)
