Overview

Silent thyroiditis must be differentiated from other causes of thyroiditis, such as De Quervain's thyroiditis, Hashimoto's thyroiditis, Riedel's thyroiditis, and suppurative thyroiditis. Silent thyroiditis must also be differentiated from other diseases which cause hypothyroidism. As silent thyroiditis may cause transient thyrotoxic symptoms, the diseases causing thyrotoxicosis must also be considered in the differential diagnosis.

Differentiating Silent Thyroiditis from other Diseases

Differentiating silent thyroiditis from other causes of thyroiditis

Silent thyroiditis must be differentiated from other causes of thyroiditis, such as De Quervain's thyroiditis, Hashimoto's thyroiditis, Riedel's thyroiditis, and suppurative thyroiditis.^[1]

Conditions	Causes	Age at onset	Pathological findings	Diagnostic approach
Silent thyroiditis	Autoimmune	All ages, peak at 30-40	Lymphocytic infiltration Lymphoid follicles	Increased TSH (hypothyroidism) and/or Decreased TSH (transient hypothyroidism) TPO antibodies present in high titer I-123 uptake usually decreased
Hashimoto's thyroiditis	Autoimmune	All ages, peak at 30-50	Lymphocytic infiltration Germinal centers Fibrosis (in some variants)	Increased TSH (hypothyroidism) TPO antibodies present in high titer I-123 uptake usually decreased
Painful subacute (De Quervain's) thyroiditis	Unknown	20-60	Giant cells Granulomas	Increased TSH (hypothyroidism) and/or Decreased TSH (Thyrotoxicosis) TPO antibodies absent or very low titer I-123 uptake decreased
Postpartum thyroiditis	Autoimmune	Childbearing age	Lymphocytic infiltration	Increased TSH (hypothyroidism) and/or Decreased TSH (transient hypothyroidism) TPO antibodies present in high titer I-123 uptake usually decreased
Riedel's thyroiditis	Unknown	30-60	Dense fibrosis	Normal TSH (euthyroidism) TPO antibodies usually present I-123 uptake decreased or normal
Suppurative thyroiditis	Infection	Children, 20-40	Abscess formation	Normal TSH (euthyroidism) TPO antibodies absent I-123 uptake normal

Differentiating silent thyroiditis from other causes of hypothyroidism

Silent thyroiditis must be differentiated from other causes of hypothyroidism on the basis of history and symptoms and laboratory findings:^[2]^[3]^[1]^[4]^[5]^[6]

Differentiating silent thyroiditis from other causes of thyrotoxicosis

Silent thyroiditis can initially present with thyrotoxicosis which must be differentiated from other causes of thyrotoxicosis.^[2]^[3]^[1]^[4]^[5]^[6]^[7]^[8]^[9]
