Background Inflammation of the orbital connective tissue, extraocular muscles and upper eyelids occurs in about 40% of patients with Graves hyperthyroidism [Graves Ophthalmopathy (GO)] while mild eye signs including upper eyelid retraction are found in as many as 25% of patients with Hashimoto thyroiditis and, occasionally, transient thyroiditis. Some workers have proposed a relationship betwee...

Riedel's thyroiditis is an extremely rare disease that is difficult to diagnose correctly using preoperative diagnostic tools because it can mimic malignant neoplasm or the fibrous variant of Hashimoto thyroiditis during preoperative physical, radiologic, and pathologic examination. We describe here a rare case of Riedel's thyroiditis in an elderly patient and its radiologic characteristics.

We establish an isomorphism between the quintic cyclic polynomials discovered by Hashimoto-Tsunogai and those arising from Kummer theory for certain algebraic tori. This enables us to solve the isomorphism problem for Hashimoto-Tsunogai polynomials and also Brumer’s quintic polynomials.

Cases of struma lymphomatosa (Hashimoto's disease) are comparatively infrequent. In 1931 Graham collected only 24 cases from the literature. This figure was brought up to 50 by McClintock and Wright in 1937, and Joll in 1939 added another series of 81 cases. A difficulty has been its differentiation from Riedel's struma, which is still a matter of dispute. So far as we are aware, no cases have ...

This paper describes a patient initially diagnosed with autoimmune thyroiditis who undergoes a diagnostic and investigatory journey.
