Abstract

Branchial cleft cysts are the most common lesions in the lateral neck with ectopic thyroid tissue found only rarely within these cysts. Over the years, multiple cases of papillary thyroid carcinoma arising from these ectopic thyroid tissues have been described in the literature with these cases sharing a normal thyroid gland on surgical and histological evaluation. Recently, however, there are three cases of papillary thyroid carcinoma in a branchial cleft cyst reported to be the result of metastasis from a thyroid primary. We present a 49-year-old female with a rare case of papillary thyroid carcinoma metastasis to a branchial cleft cyst with imaging characteristics that may prospectively suggest metastatic involvement.

摘要

鳃裂囊肿是颈部外侧最常见的病变，而异位甲状腺组织仅在这些囊肿中罕见发现。多年来，文献中描述了多例起源于这些异位甲状腺组织的乳头状甲状腺癌病例，这些病例在手术和组织学评估中均有正常甲状腺。然而，最近有三例报道称鳃裂囊肿中的乳头状甲状腺癌是甲状腺原发灶转移所致。我们报告了一例49岁女性，罕见地发生了乳头状甲状腺癌转移至鳃裂囊肿，其影像学特征可能前瞻性地提示转移累及。
