  Pituitary Tumor Diagnosis […] Tumors of the pituitary gland and other related conditions such as Rathkes cleft cyst and craniopharyngioma are often challenging to diagnose. […] An accurate pituitary tumor diagnosis usually involves hormone tests and an MRI scan of the pituitary gland. […] The first step in diagnosing a pituitary tumor is often a blood test to check for hormone imbalances. […] Most pituitary tumors (called functioning pituitary adenomas) create hormone imbalances because they secrete hormones, leading to too much of a given one in the body. […] To diagnose functional pituitary adenomas, doctors may run blood tests or other diagnostic tests to look for abnormally high amounts of: adrenocortisol (ACTH) and cortisol, growth hormone (GH) and insulin-like growth factor 1 (IGF-1), prolactin, thyroid-stimulating hormone (TSH) and thyroid hormone, luteinizing hormone (LH) and testosterone or estrogen, follicle-stimulating hormone (FSH).

  Pituitary adenomas are tumors of the anterior pituitary. Most pituitary tumors are slow-growing and benign. They are classified based on size or cell of origin. Patients with pituitary adenoma need to be evaluated by an interprofessional team that includes both endocrinology and neurosurgery to obtain the best results. […] This activity reviews the presentation, diagnosis, treatment, and management of pituitary adenomas, with particular attention to how the interprofessional healthcare team can best coordinate activity to optimize outcomes. […] Patients with pituitary adenoma need to be evaluated by a multidisciplinary team that should include endocrinology, ophthalmology and neurosurgery. […] Most pituitary adenomas are detected incidentally on routine CT imaging. An MRI with gadolinium is necessary for the distinction of a mass from an aneurysm and to assess for hemorrhage into the mass. Additionally, screening for hypopituitarism and assessing for hypersecretion is warranted. The Endocrine Society clinical practice guidelines recommend a complete biochemical assessment, even in asymptomatic patients.
