GOSERELIN INHIBITING UPTAKE ON SODIUM PERTECHNETATE Tc-99M THYROID SCAN: A CASE REPORT.

Abstract

Introduction: Thyroiditis may be induced by goserelin (a long acting analogue of gonadotropin - releasing hormone) prescribed for the treatment of pain and bleeding of endometriosis. Goserelin induced thyroiditis has a possibility of affecting thyroid function and hence may cause poor uptake on sodium pertechnetate Tc-99^m thyroid scan.

Results: This case report highlights a rare instance of a middle-aged woman with symptomatic toxic goitre whose sodium pertechnetate Tc-99^m thyroid scan uptake was inhibited by goserelin therapy.

Conclusion: Medical personnel caring for patients on goserelin need to be aware of the possibility of it affecting thyroid function.
