title: Hemiaplasia of the thyroid associated with Graves' disease: report of three cases and a review of the literature.
abstract: We recently treated three additional patients with hemiaplasia of the thyroid associated with Graves' disease, making a total of eight such cases. All eight of these patients were women and their chief complaints were goiter in five cases, whereas exophthalmos or palpebral edema were noted in six cases. All eight patients underwent surgery for Graves' disease. The left lobe was absent in six cases and the right lobe in two, whereas the isthmus was absent in six cases and the pyramidal lobe in four. A total of 102 cases of hemiaplasia of the thyroid, including our present three cases, have been reported in the world literature since 1970, with 32 of them consisting of hemiaplasia associated with hyperthyroidism. Of these, the cause of hyperthyroidism was Graves' disease in 22 cases, an autonomously functioning thyroid nodule in 7, and thyrotoxic multinodular goiter in 3. The left lobe was absent in 19 cases while the right lobe was missing in 12, and laterality was unknown in 1 case.
