PURPOSE: Silent corticotroph adenomas (SCAs) comprise 20% of all corticotroph
adenomas and 3-19% of nonfunctioning adenomas (NFAs). As they do not manifest
clinical or biochemical hypercortisolism, they are diagnosed after pathologic
examination of resected tumor tissue demonstrates positive ACTH expression. While
preoperative features are similar to those of NFAs, SCAs may have more cavernous
sinus invasion. Further, patients with SCAs tend to have more frequent and
earlier recurrences than those with NFAs, often necessitating multiple surgeries
and other modalities of treatment. This article reviews the incidence,
pathogenesis, and clinical behavior of SCAs. METHODS: A systematic literature
review was performed using PubMed for information regarding SCAs. RESULTS: Up to
date findings regarding epidemiology, pathogenesis, pathology, clinical
presentation, postoperative course, and management of patients with SCAs are
presented. CONCLUSION: This review highlights the necessity of rigorous
monitoring for recurrences and hypopituitarism in patients with SCAs.
