Empty Sella Syndrome: Clinical Significance and Management
Introduction to Empty Sella Syndrome
- The American College of Radiology indicates that an empty sella does not necessarily mean the pituitary gland is atrophied, as it may retain normal or near-normal function in many cases, with approximately 30% of patients demonstrating some degree of hypopituitarism upon testing 1, 2
Clinical Significance and Hormonal Function
- Approximately 30% of patients with empty sella demonstrate some degree of hypopituitarism upon testing, though most remain asymptomatic, according to the American College of Radiology 1, 2
- The American College of Radiology recommends comprehensive hormonal screening, including thyroid function tests, morning cortisol and ACTH, sex hormones, prolactin, and IGF-1, as approximately 30% will have some hormonal abnormality 1, 3
Diagnostic Approach
- The American College of Radiology suggests that MRI using high-resolution pituitary protocols is the preferred diagnostic modality to characterize empty sella and can confirm the diagnosis even without IV contrast 2, 3
Management and Follow-Up
- The American College of Radiology recommends careful reevaluation at 24-36 months if no hormonal alterations are detected initially, and endocrinology referral is indicated if any hormonal abnormalities are detected or if symptoms suggestive of pituitary dysfunction develop 3
