  • Diagnosis Consideration: A multicystic mass in the sella with a thin enhancing septation is suggestive of a Rathke cleft cyst or a cystic pituitary adenoma.
  • Imaging Characteristics:
    • Rathke cleft cysts typically present as well-defined cystic lesions with thin walls and may show minimal enhancement.
    • Cystic pituitary adenomas can also appear multicystic and may have enhancing septations.
  • Clinical Correlation: Evaluate for symptoms such as headaches, visual field defects, or hormonal imbalances to aid in diagnosis.

Clinical Bottom Line: Further imaging and clinical correlation are essential to differentiate between these entities, as management may vary based on the definitive diagnosis.
