Clinical Report: Pediatric Case Study of ACTH-Secreting Pituitary Adenoma
Background
ACTH-secreting pituitary adenomas are rare in pediatric populations, accounting for less than 0.01% of cases. These tumors can lead to Cushing's disease, which presents diagnostic challenges due to nonspecific symptoms. Understanding their clinical and imaging manifestations is crucial for timely diagnosis and management.

Late-night Serum Cortisol
1019.16 nmol/L
4 PM Cortisol
1172 nmol/L
Serum Potassium
2.16–3.0 mmol/L

Key Findings
A 13-year-old boy presented with severe headache, anuria, and hypertensive crisis.
Biochemical evaluation showed elevated ACTH and disrupted cortisol rhythm.
MRI revealed a cystic lesion in the left adenohypophysis consistent with apoplexy.
Histopathology confirmed the diagnosis of an ACTH-secreting adenoma.
Transsphenoidal resection and hormone replacement led to stable remission at 3-year follow-up.
Clinical Implications
Surgical intervention and hormonal management are critical for achieving favorable outcomes.
Conclusion
This case underscores the rarity and complexity of pediatric ACTH-secreting pituitary adenomas, highlighting the need for heightened diagnostic awareness among clinicians.
