 ===== Summary =====
+Empty sella is characterized by CSF herniation into the sella turcica with compression or flattening of the pituitary gland. It may be primary (due to incomplete diaphragma sellae allowing arachnoid herniation) or secondary (after surgery, infarction, apoplexy, or irradiation). Frequently incidental, but may correlate with idiopathic intracranial hypertension or endocrine dysfunction.
