title: Amyloid goiter: preoperative scintigraphic diagnosis using Tc-99m pyrophosphate.
abstract: Amyloid goiter is a rare clinical entity. The diagnosis is rarely made preoperatively because clinical and laboratory findings are nonspecific. We report two cases of amyloid goiter in whom the diagnosis was made preoperatively using Tc-99m pyrophosphate scintigraphy.
