Which statement about precocious puberty is most accurate?

• A. Is more common in boys
• B. Usually idiopathic in girls
• C. CNS tumors are a common cause of central precocious puberty in girls
• D. Precocious puberty can affect multiple domains of development

Answer: (C)

Central precocious puberty occurs when the brain triggers the early activation of the hypothalamic–pituitary–gonadal axis, leading to premature secondary sexual characteristics. The causes of central precocious puberty fall into idiopathic cases and cases driven by CNS pathology. In girls, most central cases are idiopathic, but CNS lesions—including tumors—are a recognized cause and can initiate early GnRH release. This makes the statement about CNS tumors being a possible cause accurate, and it highlights why clinicians consider brain imaging when central precocious puberty is diagnosed, especially if there are neurologic symptoms or in very young children. Understanding that CPP can be driven by brain pathology helps explain why management isn’t just about suppressing puberty, but also about identifying and addressing any underlying CNS issue to prevent longer-term consequences.
