Complete remission after glucocorticoid therapy in a patient with primary hypophysitis

Area of Science:

• Endocrinology
• Immunology
• Radiology

Background:

• Primary hypophysitis is a rare inflammatory condition affecting the pituitary gland.
• Treatment options include observation, immunosuppressants, and surgery, with glucocorticoids as first-line therapy.
• Non-responsiveness and recurrence are significant challenges in managing hypophysitis.

Purpose of the Study:

• To report a case of primary hypophysitis with an excellent response to a single course of glucocorticoids.
• To discuss the potential efficacy of steroid therapy in mild-to-moderate cases of hypophysitis.

Main Methods:

• A 30-year-old male patient with acute onset symptoms and a pituitary mass on MRI was treated with methylprednisolone.
• Clinical presentation, hormonal evaluation, and serial cranial MRI were used to assess treatment response.
• Hormonal function and pituitary mass regression were monitored over six months.

Main Results:

• The patient presented with headaches and a pituitary mass causing optic chiasm compression.
• Hormonal evaluation indicated anterior pituitary dysfunction, excluding the growth hormone axis.
• Cranial MRI showed complete regression of the pituitary mass after two months of methylprednisolone therapy.
• Full recovery of pituitary functions was observed after six months.

Conclusions:

• Glucocorticoid therapy can be highly effective in achieving remission for primary hypophysitis, particularly in mild-to-moderate cases.
• A single course of steroids may be sufficient for treatment, even at lower doses.
• Individualized treatment strategies are crucial given the varied clinical course of hypophysitis.
