These tumors are associated with an aggressive clinical course because of a tendency for rapid progression and invasive growth, as well as a high recurrence rate. We present a 41-year-old woman without Cushingoid symptoms who presented with headache, bitemporal hemianopia, and diplopia. MRI revealed a mass extending into the suprasellar region, measuring approximately 2 × 4 cm, with internal necrotic areas and post-contrast enhancement. Following transsphenoidal resection, immunohistochemical staining demonstrated positivity for adrenocorticotropic hormone, confirming the diagnosis of a silent corticotroph pituitary neuroendocrine tumor. This case highlights the importance of recognizing silent corticotroph pituitary neuroendocrine tumors, the treatment approach, and long-term follow-up. </p>}, number={2}
