Hashimoto's Thyroiditis with Subclinical Hypothyroidism and Multi-System Symptoms: A Case of a Middle-Aged Male

Hashimoto's thyroiditis (HT) is a chronic autoimmune disease with lymphocytic infiltration of the thyroid gland and autoantibodies against endogenous components. A 45-year-old male professor at an academic institution with positive family history for autoimmune diseases among his brother and sister came to clinical hospital because of unspecific systemic symptoms, elevated TSH, low normal Free T4 (fT4), positivity autoantibodies against the thyroid gland. The biochemical signs of inflammatory process were shown in a report and image form ultrasound of thyroid gland, this indicates enlargement and thyroiditis. The case was diagnosed by elevated TSH, positive anti-TPO and thyroid ultrasound as subclinical stage of HT.
