Iodine-induced subacute thyroiditis with thyrotoxicosis presenting as fever of unknown origin.
A 26-year-old woman with features of bulimia nervosa presented with fever of unknown origin, hepatomegaly, marked leukocytosis, and increased erythrocyte sedimentation rate. Following prolonged observation, slight tenderness over the thyroid gland and signs of thyrotoxicosis occurred. A thyroid scan demonstrated no isotope uptake and the patient admitted abusing an organic iodine preparation in order to control her weight. The diagnosis of iodine-induced subacute thyroiditis with thyrotoxicosis was, therefore, considered. A brief course of low-dose steroids normalized both thyroid function and hematological parameters. On followup evaluation, urinary iodine excretion and thyroid function tests were normal.
