Summary
A rare case of hypothalamic hamartoma caused true precocious puberty in an infant. Surgical removal normalized puberty and hormone levels, suggesting a safe treatment option.
Area of Science:
- Pediatric Endocrinology
- Pediatric Neurosurgery
- Neuroendocrinology
Background:
- True precocious puberty is diagnosed when the hypothalamic-pituitary-gonadal axis activates prematurely.
- Hypothalamic hamartomas are rare congenital tumors that can cause various neurological and endocrine disorders.
Observation:
- A 7-month-old girl presented with clinical signs of true precocious puberty.
- Hormonal evaluation revealed elevated luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels, with appropriate response to gonadotropin-releasing hormone (GnRH) stimulation.
Findings:
- The patient had a hypothalamic hamartoma causing the precocious puberty.
- Subtotal surgical resection of the hamartoma led to normalization of clinical and hormonal abnormalities.
- Microsurgical techniques were employed, and the procedure appeared safe.
Implications:
- This case highlights hypothalamic hamartoma as a treatable cause of precocious puberty in infants.
- Surgical intervention, when performed with microsurgical precision, offers a safe and effective treatment modality.
- Further research into the neurosurgical management of such rare pediatric endocrine disorders is warranted.
