Excerpt

The thyroid, like any other structure, may be the seat of an acute or chronic suppurative or non-suppurative inflammation. Various systemic infiltrative disorders may leave their mark on the thyroid gland as well as elsewhere. Infectious thyroiditis is a rare condition, usually the result of bacterial invasion of the gland. Its signs are the classic ones of inflammation: heat, pain, redness, and swelling, and special ones conditioned by local relationships, such as dysphagia and a desire to keep the head flexed on the chest in order to relax the paratracheal muscles. The treatment is that for any febrile disease, including specific antibiotic drugs if the invading organism has been identified and its sensitivity to the drug established. Otherwise, a broad-spectrum antibiotic may be used. Surgical drainage may be necessary and a search for a pyriform sinus fistula should be made, particularly in children with thyroiditis involving the left lobe. Important to differentiate from the acute bacterial infection of acute suppurative thyroiditis (AST), is subacute (granulomatous) thyroiditis (SAT) which is far more common than AST and is characterized by a more protracted course, usually involving the thyroid symmetrically. The gland is also swollen and tender, and the systemic reaction may be severe, with fever and an elevated erythrocyte sedimentation rate. During the acute phase of the disorder, tests of thyroid function often disclose a suppression of TSH, increased serum concentrations of T4, T3, and thyroglobulin while a diminished thyroidal RAIU is observed. The cause of SAT has been established in only a few instances in which a viral infection has been the initiating factor. There may be repeated recurrences of diminishing severity. Usually, but not always, the function of the thyroid is normal after the disease has subsided. Subacute thyroiditis may be treated with rest, non-steroidal anti-inflammatory drugs or aspirin, and thyroid hormone. If the disease is severe and protracted, it is usually necessary to resort to administration of glucocorticoids, but recurrence may follow their withdrawal. It is precisely the observational nature of SAT therapy combined with the use of glucocorticoids that make it so critical to rule out the bacterial etiology of AST in the patient presenting with a painful thyroid. Riedel's thyroiditis is a chronic sclerosing replacement of the gland that is exceedingly rare. The process extends to adjacent structures, making any surgical intervention very difficult and potentially harmful. The exact cause of Riedel’s thyroiditis remains unknown, and no specific treatment is available beyond limited resection of the thyroid gland to relieve the symptoms of tracheal or esophageal compression. The use of anti-inflammatory medical treatments has been demonstrated to have significant benefits to outcome. Sarcoidosis may involve the thyroid, and amyloid may be deposited in the gland in quantities sufficient to cause goiter. In all of these diseases, it may be necessary to give the patient levothyroxine replacement therapy if the function of the gland has been impaired.
