Diagnostic Considerations

Other problems to be considered

The radiologic pituitary lesion may reflect nonadenomatous causes, which include cysts (eg, Rathke cleft cyst, which is usually in the midline), vascular changes, or other local pathological neoplastic or inflammatory processes. [14, 15]

As with all pituitary adenomas, it may be part of a multiple endocrine neoplasia type 1 (MEN1) syndrome. Family history is usually present. Other hypersecretory states, such as hyperparathyroidism, may need to be assessed.
