Background: Pituitary macroadenoma is often confused with pituitary hyperplasia, a benign proliferation of thyrotropic cells due to prolonged peripheral hypothyroidism.
Case Presentation: We report the case of a 17-year-old female initially diagnosed with a pituitary macroadenoma, in whom we concluded that pituitary hyperplasia was secondary to Hashimoto’s thyroiditis.
Conclusion: Differential diagnosis is essential to avoid unnecessary surgery, as hormone replacement therapy can lead to complete regression of the mass.
