Riedel's thyroiditis presenting with hypothyroidism and hypoparathyroidism: dramatic response to glucocorticoid and...

Area of Science:

• Endocrinology
• Rheumatology
• Head and Neck Surgery

Background:

• Riedel's thyroiditis is a rare, invasive fibro-inflammatory thyroid condition.
• It often mimics thyroid cancer due to a hard thyroid mass.
• Associated complications include hypothyroidism and hypoparathyroidism.

Observation:

• A patient presented with Riedel's thyroiditis, hypothyroidism, hypoparathyroidism, and bilateral vocal cord paralysis.
• The presentation mimicked anaplastic thyroid carcinoma.
• The patient experienced severe disease manifestations.

Findings:

• High-dose prednisone and levothyroxine therapy resulted in a dramatic response.
• The patient showed recovery of parathyroid and vocal cord function.
• This highlights the effectiveness of early combination treatment.

Implications:

• Early combination therapy may be crucial for managing severe Riedel's thyroiditis.
• Prompt treatment can reverse serious complications like hypoparathyroidism and vocal cord paralysis.
• This case underscores the importance of considering Riedel's thyroiditis in the differential diagnosis of hard thyroid masses.
