# Refractory Hypothyroidism: Unexpected Outcome During Treatment of Giant Cell Arteritis

## TL;DR

This paper discusses a rare case where a patient with giant cell arteritis did not respond well to levothyroxine treatment for hypothyroidism.

## Contribution

The study highlights the challenge of managing refractory hypothyroidism in the context of giant cell arteritis.

## Key findings

- The patient's TSH levels remained abnormal despite levothyroxine treatment.
- Long-term follow-up showed persistent difficulty in restoring normal thyroid function.
- This case emphasizes the need for careful management in such complex patients.

## Abstract

Refractory hypothyroidism is not uncommon in patients treated with oral levothyroxine, and it represents a challenge for clinicians as regards a physiopathological diagnosis and the most appropriate long‐term therapeutic management in order to restore normal TSH concentrations.
