**4. Clinical presentation**

Pituitary adenomas may present with multiple different manifestations. These include: hormonal hypersecretory signs and symptoms, pituitary dysfunction, mass effect on surrounding neuronal structures, or may present acutely with headache and altered mental status due to pituitary apoplexy. However, asymptomatic pituitary adenomas discovered incidentally on brain MRI are not uncommon. It was found that 10% of general adult population may have asymptomatic pituitary adenoma (pituitary incidentalomas) [5].
