Age at puberty onset was &amp;lt;6 years in 116 and 6-8 years in 654. CNS lesions were followed until final decision(6.2 \u00b1 3.1 years). Potential predictors of CNS lesions were evaluated by univariate analyses.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>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; neither required intervention over follow-up of 6 and 3.5 years respectively. Age at breast development &amp;lt;6 years (odds ratio [OR] 2.38; 95% CI 1.08-5.21) and the peak luteinizing hormone\/follicle-stimulating hormone (LH\/FSH) ratio &amp;gt;0.6 (OR 3.13; 95% CI 1.02-9.68) were significantly associated with CNS lesions. However, both patients with neoplastic lesions were &amp;gt;6 years old.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Although age and LH\/FSH ratio are significant predictors of CNS lesions, their predictive power is weak.
