Abstract

Adenolipomas or thyrolipomas are well-circumscribed benign neoplasm characterized by the presence of mature adipose tissue and glandular elements. They are a rare finding, first described by Trites [1]. In two studies [2, 3] the prevalence was about 1%. Kitagawa et al. [4] found that adenolipomas predominate in women (1,6:1) in the sixth decade. Both lobes are equally involved; nodules arising in the isthmic region are rare [4]. Patients are usually euthyroid and presenting swelling of the anterior neck with or without compression symptoms [5–7]. Adenolipomas may be associated with nodular goiter [4, 6]. US represents the first line examination to evaluate the thyroid gland and regional anatomy and has become an important diagnostic tool in the assessment of thyroid nodules.
