Endoscopic transsphenoidal surgery for isolated fibrous dysplasia of the clivus.

INTRODUCTION

Fibrous dysplasia is a non-neoplastic disorder of bone, related to abnormal proliferation of fibro-blasts.

CASE REPORT: We report a 41-year-old female who presented with hyperprolactinaemia and an incidental clival lesion on MR scan. This was sub-totally resected via an endoscopic transsphenoidal approach and fibrous dysplasia was confirmed histologically. Her postoperative re-covery was un-eventful and at 8 months follow-up, she remains well, other than for the intermittent headaches and with no pituitary hormone deficiencies.

CONCLUSION

The present case highlights the need to consider fibrous dysplasia in the differential diagnosis of isolated clival lesions.
