Neuroendocrine tumors (NET) originate from the diffuse neuroendocrine system. These can arise in almost every organ of the body, although they are most commonly found in the gastrointestinal tract and respiratory system. The skull base and sellar region are extremely rare sites for neuroendocrine carcinoma. Intracranial originating is lower than 0.74 %. A 55year old male was admitted in the neurosurgery department of Owaisi Group of Hospitals (PEH) with chief complaint of severe headache for 15 days, associated with giddiness, nausea and left eye vision disturbance. MRI showed Pituitary macroadenoma. Surgery was performed and the excised specimen of Pituitary adenoma was sent for HPE which revealed that the lesion was a Neuroendocrine tumor.
