[Hypothalamic hamartoma in children]

Area of Science:

• Pediatric Endocrinology
• Pediatric Neurology
• Neuroscience

Context:

• Hypothalamic hamartomas are rare brain malformations causing central precocious puberty (PP).
• This study analyzes 27 pediatric cases, one of the largest series globally.
• Understanding the relationship between hamartoma location and endocrine/neurologic symptoms is crucial.

Purpose:

• To correlate specific hypothalamic hamartoma locations with distinct clinical manifestations, including central precocious puberty (PP).
• To evaluate the efficacy and risks of surgical versus medical treatments for PP in children with hypothalamic hamartomas.

Summary:

• Parahypothalamic (peduncular) hamartomas primarily cause PP.
• Intrahypothalamic (sessile) hamartomas lead to PP and convulsive symptoms like laughter attacks.
• Suprahypothalamic lesions are associated with diencephalic disorders such as obesity and diabetes insipidus.
• Medical treatment using gonadotropin-releasing hormone analogues demonstrates high efficacy.
• Surgical intervention shows low efficacy and high complication rates.

Impact:

• Provides critical insights into the neuroanatomical basis of endocrine disorders in children.
• Establishes medical treatment as the preferred, highly effective approach for precocious puberty due to hypothalamic hamartomas.
• Highlights the risks associated with surgical intervention, guiding clinical decision-making.
