    Context: Central precocious puberty (CPP) may arise from central nervous system (CNS) lesions in a few affected girls. Recently, the incidence of girls with CPP has increased mostly in 6-8 year olds, in whom the necessity of magnetic resonance imaging (MRI) is debated. Objective: To investigate the frequency, long-term outcome and potential predictors of CNS lesions in a large cohort of girls with CPP. Methods: A multicenter cohort of 770 Turkish girls with CPP who had systematic cranial MRI between 2005 and 2017. Age at puberty onset was <6 years in 116 and 6-8 years in 654. CNS lesions were followed until final decision(6.2 +/- 3.1 years). Potential predictors of CNS lesions were evaluated by univariate analyses. Results: A total of 104/770 (13.5\%) girls had abnormal brain MRI. Of these, 2.8\% were previously known CNS lesions, 3.8\% had newly detected and causally related CNS lesions, 3.1 \% were possibly, related and 3.8\% were incidental. Only 2 (0.25\%) neoplastic lesions (1 low grade glioma and 1 meningioma) were identified
