Another treatment option is injection of ethanol into the nodules. The usage of terminology for types of goiter has varied over the past century.

Isobutyryl-coenzyme A dehydrogenase deficiency Isobutyryl-coenzyme A dehydrogenase deficiency Isobutyryl-coenzyme A dehydrogenase deficiency, commonly known as IBD deficiency, is a rare metabolic disorder in which the body is unable to process certain amino acids properly. People with this disorder have inadequate levels of an enzyme that helps break down the amino acid valine, resulting in a buildup of valine in the urine, a symptom called valinuria. Defects in the "ACAD8" gene cause isobutyryl-coenzyme A dehydrogenase deficiency. The "ACAD8" gene provides instructions for making an enzyme that plays an essential role in breaking down proteins from the diet. Specifically, the enzyme is responsible for processing valine,
