Pediatric silent corticotroph pituitary adenoma and role for proton therapy: case report

Restricted access

Tumors involving the sella are commonly craniopharyngiomas, optic pathway gliomas, or pituitary adenomas. Functioning adenomas are expected, with prolactinomas topping the differential. The authors present the case of a silent corticotroph adenoma, which has not been described in the pediatric population, and they detail the use of proton therapy, which is also novel.

ABBREVIATIONS ACTH = adrenocorticotrophic hormone; CTV = clinical target volume; EVD = external ventricular drain; FSH = follicle-stimulating hormone; GH = growth hormone; IGF-1 = insulin-like growth factor–1; NFA = nonfunctioning adenoma; RT = radiation therapy; SCA = silent corticotroph adenoma.
