Subacute thyroiditis is generally felt to have a viral etiology, and the diagnosis is usually obvious when the patient presents with a diffusely enlarged and very tender thyroid gland associated with elevated free T4 levels, elevated sedimentation rate, low radioiodine uptake and/or nonvisualization on scan and often some systemic symptoms. Subacute thyroiditis can be unilateral or focal (1,2)....

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 diagno...

Objective(s):The aim of this study was to determine whether technetium (99mTc) uptake is a relevant method for the differential diagnosis of Graves disease and subacute thyroiditis and calculate its cutoff value in case of its relevancy. Methods: A total of 69 patients, who were followed up (>3 months) in our hospital for thyrotoxi...

Our purpose in this paper is to make a case for the need to question whether Riedel's thyroiditis is in fact a rare variety of subacute thyroiditis. Total thyroidectomy was performed on a patient with a huge thyroid mass. The histopathological diagnosis was Riedel's thyroiditis with classical lymphoplasmacytic infiltration destroying thyroid tissue and invading perithyroidal soft tissue. Howeve...

A 52-year-old man presented with subacute thyroiditis and showed an intensely hypermetabolic thyroid lesion on (18)F-FDG PET/CT. The patient also had coexisting chronic lymphocytic thyroiditis. The lesion of subacute thyroiditis revealed an SUV(max) of 9.1 g/mL and was ill-defined, heterogeneous, markedly hypoechoic, and hypovascular on US. Biopsy demonstrated histologic findings of subacute th...

BACKGROUND A study had reported that a low TSH level is associated with elevated plasma fibrinogen (FIB) levels. Our purpose was to investigate the role of FIB in the differential diagnosis of thyrotoxicosis. METHODS The data of 104 patients with primary thyrotoxicosis at the First Hospital of China Medical University from July 2010 to March 2011 were analyzed and divided into three groups: 4...

We saw a total of 4 episodes of the recurrence of subacute thyroiditis in 3 patients out of 222. The recurrent episodes were similar to the first episodes of subacute thyroiditis. The titers of various viral antibodies were not increased significantly during the clinical course of the recurrence. Regarding the HLA typing, A26, B35 and C3 were positive in all 3 patients. The association between ...

Subacute thyroiditis is not so common, but failure to diagnose may lead to unnecessary therapy and suffering cases of subacute thyroiditis arc described and diagnosis discussed.

INTRODUCTION Subacute thyroiditis is a self-limited, inflammatory viral thyroid disease which presents with neck pain, usually accompanied by systemic symptoms. On the other hand, thyroid storm is a clinical condition of severe sudden hyperthyroidism accompanied by physiologic de-compensation. We presented a 29-year-old male with features of subacute thyroiditis and thyroid storm who is the thi...

Context: Subacute thyroiditis has been classified as an auto inflammatory condition and occurs mainly due to a viral infection. According the pathogenesis of SARS-CoV2 infection, which is based on uncontrolled immune response, several studies have investigated possible association between subacute thyroiditis. In this regard, we aimed review organize these studies. Evidence Acquisition: First, ...
