Background:
Pituitary hyperplasia is an infrequent cause of visual disturbance and few such cases have been reported in the literature.
Case description:
We describe the case of a 16-year-old female who presented with a short history of progressive headache and visual blurring. Examination revealed markedly constricted visual fields. Imaging revealed an enlarged pituitary gland. Hormonal panel was normal. Following endoscopic endonasal transsphenoidal biopsy and decompression of the optic apparatus, an immediate improvement in vision was noted. Final histopathological examination revealed pituitary hyperplasia.
Conclusion:
In patients with pituitary hyperplasia, visual deficit, and no identifiable reversible causes, surgical decompression can be considered to preserve vision.
