“…Marin et al [16] described 2 cases of RT with hypothyroidism and hypoparathyroidism. Anti-microsomal antibodies were positive in their patients, but the levels were lower than our case, and there was no concomitant follicular neoplasm.…”

A Case of Asymptomatic Riedel Thyroiditis with Follicular Adenoma in a Patient with a Multinodular Goiter: An Unusual Association

Background: Riedel’s thyroiditis (RT) is a rare inflammatory disease that results in fibrosis of the thyroid gland and invasion to the surrounding structures of the neck. Follicular adenoma (FA) of the thyroid is the most common benign neoplasm of the gland. Patient Findings: A 42-year-old woman was referred to the outpatient clinic due to a multinodular goiter and thyroiditis. The patient was euthyroid and thyroid function tests were within normal limits. Thyroid antibodies (thyroid peroxidase antibody and thyroglobulin antibody) were high. Thyroid ultrasonography showed multiple iso-hypoechoic nodules and thyroiditis. Fine-needle aspiration cytology was performed, and it was consistent with ‘suspicious for a follicular neoplasm’ according to the Bethesda system. Due to the clinical findings, which included weight loss and sweating, and the cytological results indicative of a follicular neoplasm, the patient underwent a total thyroidectomy. The histopathological diagnosis was RT associated with FA. The patient was started on thyroid hormone (thyroxine) replacement therapy after surgery and was evaluated for additional fibrosis related to RT. Conclusions: To our knowledge, this is the first case of RT associated with FA in an asymptomatic patient with a multinodular goiter and high thyroid antibodies reported in the literature.

“…Fibrosis characteristically invades and encloses the adjacent structures in the neck extending beyond the limits of thyroid capsules. It is important to distinguish between Riedel's thyroiditis and thyroid carcinoma; however, it is clinically impossible to make an absolute diagnosis [10,11]. Therefore, surgical biopsy and treatment is commonly used.…”

Riedel's Thyroiditis in a Patient with Recurrent Subacute Thyroiditis: A Case Report and Review of the Literature

et al. 2007

Abstract. Riedel's thyroiditis is a rare form of chronic thyroiditis, characterised by a fibroinflammatory process that partially destroys the thyroid and often involves surrounding tissues. The relationship of Riedel's thyroiditis to other forms of thyroiditis is not clear. A case of Riedel's thyroiditis in a 51-year-old woman presenting with symptoms of subacute thyroiditis, is reported. She was diagnosed with subacute thyroiditis based on clinical manifestation and laboratory results. She was treated with glucocorticoids for six weeks, and then followed-up for 12 months. Three years later, she visited with tenderness and enlargement of thyroid mass, and laboratory and radiology findings suggested that she had a malignant thyroid tumor as well as subacute thyroiditis. After thyroidectomy, histopathologic findings showed that she had Riedel's thyroiditis in the presence of subacute thyroiditis. Until now, few cases of Riedel's thyroiditis in patients with a history of subacute thyroiditis have been reported in the literature. Although the etiology of Riedel's thyroiditis is unknown, it may develop in the course of subacute thyroiditis. Case ReportA 51-year-old woman presented in our clinic with sudden onset of painful swelling in anterior neck. She had been treated for upper respiratory infection at another clinic 2 weeks prior to this visit. Her height was 156 cm, weight 61 kg, blood pressure 140/90 mmHg, pulse rate 106 per minute, respiration rate 18 per minute, and body temperature 37.1°C. Her thyroid was diffusely enlarged, quite firm, and tender. A fairly fixed nodule (2.0 × 1.0 cm) was palpated in the left thyroid gland. Abnormal laboratory findings included elevated erythrocyte sedimentation rate (ESR) of 61 mm/hr, and elevated serum T 3 of 209 ng/dL (normal, 84-157 ng/dL), elevated serum T 4 of 13.0 µg/dL (normal, 4.7-9.3 µg/dL), and a decreased TSH level of 0.1 µIU/mL (normal, 0.39-3.68 µIU/mL). Both anti-thyroperoxidase (anti-TPO) antibody and antithyroglobulin (anti-Tg) antibody were negative and anti-TSH receptor antibody was also negative. Thyroid radioiodine uptake ratio was 3.42% after 2 hours and 3.10% after 24 hours. Fine needle aspiration cytology (FNAC) of the suspect thyroid nodule was negative, however, there was infiltration of lymphocytes and leukocytes, and several giant cells were observed.

“…While both RT and IgG4-RD have been reported to occur more frequently in patients with hypothyroidism and those who are highly positive for anti-thyroid antibodies, RT is more common in women between 30 and 50 years of age [8,7,[24][25][26], and IgG4-RD has a higher incidence in men older than 50 years [17,27]. Our 10 Japanese patients with RT were predominantly females (70%), aged 30 to 60 years, which was rather consistent with the clinical profile of RT.…”
