In this review, we discuss pituitary adenomas (PA), which account for 10-25% of the intracranial tumours. Despite their benign nature, PA often show invasive growth. Pressure on neighbouring structures may cause hypopituitarism or vision field impairment. For PA, except prolactinomas, surgical treatment is first choice. The primary surgical technique is transsphenoidal surgery. Pituitary function, vision and post-operative magnetic resonance imaging scan is evaluated in a multidisciplinary team of neurosurgeons and endocrinologist 6-8 weeks post-operatively. Follow-up and treatment of pituitary adenomas is highly specialised and requires a team of dedicated endocrinologists and neurosurgeons.
