Advanced imaging is catching more pituitary tumors than ever before. Often these tumors — once thought to be rare — are found when a patient is being tested for something else. As many as one in four people may have pituitary adenomas without any symptoms. Most of these will be benign but will merit evaluation and monitoring. Other than these incidental findings, pituitary disorders are often challenging to diagnose, as many of the complaints are nonspecific or could arise from multiple pathologies.
Symptoms that raise suspicion of a pituitary tumor
Pituitary tumors and other pituitary disorders can have several signs, but most often fall into these categories:
- Neurologic symptoms when a pituitary lesion is large (headaches, loss of peripheral vision, double vision)
- Hormonal deficiencies (fatigue, unintentional weight change, nausea, hair loss, infrequent menstrual periods, excessive thirst and urination)
- Hormonal overproduction (menstrual irregularities, milky breast discharge, fatigue, weight gain, hirsutism, enlargement of hands and feet, excessive sweating, purple stretch marks and bruising)

Multidisciplinary approach to pituitary diseases
Multidisciplinary management of pituitary tumors in a pituitary center of excellence has been shown to improve both short and long term clinical outcomes.
The OHSU Pituitary Center treats more than 500 patients a year at a multidisciplinary clinic that teams neuroendocrinologists, neurosurgeons, neuro-ophthalmologists and others. We are available for urgent referrals and have several clinical trials underway. Our pituitary care team is committed to providing excellent patient care, contributing to knowledge about pituitary diseases and partnering with community doctors to care for patients.
