[Hypothalamic hamartoma in children]
Insights
This study examines children with precocious puberty (PP) caused by hypothalamic hamartomas. Medical treatment is highly effective for PP, while surgery carries significant risks and low efficacy.
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.
Abstract:
The paper presents the data of examination and treatment of children with pubertas precox (PP) resulting from hypothalamic hamartoma, a rare malformation of the brain. It analyzes the results of 27 cases that is one of the largest series of cases in the world literature. Of the greatest interest are the clinical and anatomic comparisons presented by the authors, which make it possible to define the involvement of different hypothalamic structures in the development of specific endocrine disorders. When located parahy-pothalamically, hamartomas (a peduncular type) are characterized by the symptoms of PP; when located intrahypothalamically (a sessile type), in addition to PP, there are convulsive typical symptoms (compulsive laughter attacks). At the suprahypothalamtc site, there are commonly diencephalic disorders (obesity, diabetes insipidus). The paper provides the results of surgical and hormonal treatment (the use of long-acting luteinizing hormone-releasing hormone analogues), evidence for the high efficiency of medical treatment and the low efficiency attended by a high risk of complications, surgical treatment.

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
