We describe a rare case of lymphocytic hypophysitis, a pituitary gland inflammation. This condition caused hypopituitarism and diabetes insipidus, with imaging showing a sellar mass and thickened pituitary stalk.

Area of Science:

  • Endocrinology
  • Neuroimaging
  • Pathology

Background:

  • Lymphocytic hypophysitis is a rare inflammatory condition affecting the pituitary gland.
  • It can present with symptoms of hypopituitarism and diabetes insipidus.
  • Distinguishing it from pituitary adenoma is crucial for appropriate management.

Observation:

  • A 52-year-old male presented with hypopituitarism and diabetes insipidus.
  • Magnetic resonance imaging (MRI) revealed an expanding sellar mass.
  • Pituitary stalk thickening with homogeneous enhancement was noted on contrast-enhanced MRI.

Findings:

  • The radiological features, including the sellar mass and pituitary stalk enhancement, are characteristic of lymphocytic hypophysitis.
  • These imaging findings can aid in differentiating this condition from pituitary adenoma.

  • The case highlights the importance of integrating clinical presentation with advanced imaging.

    • Implications:

    • Accurate diagnosis of lymphocytic hypophysitis is essential for timely and effective treatment.
    • Understanding the unique radiological features can improve diagnostic accuracy.
    • This case contributes to the literature on rare pituitary inflammatory diseases.
