Background: Craniopharyngioma is a common intracranial tumour in children. Clinical manifestations are related to hypothalamic/pituitary deficiencies, visual impairment, and increased intracranial pressure. Defects in pituitary function cause shortages of growth hormone, gonadotropin, corticotropin, thyrotropin, and vasopressin, resulting in short stature, delayed puberty, feebleness, lethargy, polyuria, etc. However, manifestations involving precocious puberty (PP) are rare.
Case report: In both patients, surgical resection was performed after the diagnosis of craniopharyngioma, and breast development occurred postoperatively at one month in one patient and at one year and three months in the other patient. Central precocious puberty (CPP) was diagnosed via relevant examinations. Leuprorelin was injected subcutaneously every 28 days, and changes in height, weight, bone age, gonadal ultrasound and sex hormones were recorded. During the follow-up of the two children, the sex hormone levels were significantly reduced, and significant acceleration in bone age was not observed.
Conclusions: CPP was induced by craniopharyngioma surgery, and treatment with gonadotropin-releasing hormone analogues (GnRHa) inhibited sexual development and bone age progression. More attention should be given to monitoring for CPP during long-term follow-up of craniopharyngiomas in the clinic.
