Diagnostic Considerations

Sellar masses other than adenomas should be considered based on the radiologic appearance, concomitant symptoms, and biochemical testing. Sellar lesions can be cystic, benign, malignant, vascular, or inflammatory.

Differentials include:

  • Pituitary hyperplasia (lactotroph hyperplasia during pregnancy)
  • Rathke cyst
  • Dermoid cyst
  • Meningioma
  • Craniopharyngioma
  • Primary central nervous system (CNS) lymphoma
  • Germ cell tumor
