Thyroid sonography has been used as a major diagnostic technique for the evaluation of thyroid nodules. Several sonographic features such as hypoechongenicity, an irregular margin and micro calcifications have been introduced as potential predictors for the presence of a thyroid malignancy in solid thyroid nodules. However, there have been few studies on sonographic features as predictors of a diagnosis of cystic thyroid nodules. Among 230 nodules surgically removed in our hospital, we reviewed preoperative ultrasound examinations of 59 cystic nodules. Thyroid nodules were classified as Eccentric type (E), Concentric type (C), or Multiseptate type (M) in their configuration depending on the position of the solid and cystic components. The eccentric type was subdivided into either an acute angle (Ea) or a blunt (Eb) angle, depending on the angle between the solid component and the adjacent cyst wall. We also investigated the presence or absence of calcification, echo level, margin of the cyst and the solid part. Ea, Eb and solid component ≥ 50%, M and irregular margin or micro calcification were associated with malignancy."},{"@language":"ja","@value":"甲状腺腫瘍は，充実性腫瘍と嚢胞性腫瘍（嚢胞性病変を含む）に大きく分けられる。甲状腺超音波検査は甲状腺腫瘍の診断において欠かせないものであり，低エコー，辺縁不整，微小石灰化は悪性を示唆する所見といわれている。しかしこれらは主に充実性腫瘍における所見であり，嚢胞性腫瘍に関する報告は少ない。今回，当院で施行した甲状腺手術症例230例のうち嚢胞性腫瘍59例について術前超音波所見を見直し，悪性を疑う所見を検討した。超音波所見から充実部分が腫瘍壁に偏在するものをEccetric type（E），嚢胞部分が腫瘍の中心にあるものをConcentric type（C），多数の隔壁があるものをMultiseptate type（M）と分類した。Eccetric typeはさらに充実部分と腫瘍壁の接する角度が鋭角のものEccentric and acute angle type（Ea）と鈍角のものEccentric and blunt angle type（Eb）に分類し，検討した。Ea，Eb and「充実部分50%以上」，M and「充実部分と嚢胞部分の境界不整or微小石灰化」を示す例では悪性の可能性が示唆された。"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410572171378642816","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000283592875"}],"foaf:name":[{"@language":"en","@value":"Komatsu Ai"},{"@language":"ja","@value":"小松 愛"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Otorhinolaryngology, Yokosukakyousai Hospital"}]},{"@id":"https://cir.nii.ac.jp/crid/1410572171378642818","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000283592876"}],"foaf:name":[{"@language":"en","@value":"Suzuki Kazumasa"},{"@language":"ja","@value":"鈴木 一雅"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Otorhinolaryngology, Yokosukakyousai Hospital"}]},{"@id":"https://cir.nii.ac.jp/crid/1410572171378642817","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000283592877"}],"foaf:name":[{"@language":"en","@value":"Fujita Yoshifumi"},{"@language":"ja","@value":"藤田 芳史"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Otorhinolaryngology, Yokosukakyousai Hospital"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"13495747"},{"@type":"EISSN","@value":"18818382"}],"prism:publicationName":[{"@language":"en","@value":"Toukeibu Gan"},{"@language":"ja","@value":"頭頸部癌"},{"@language":"en","@value":"Toukeibu Gan"},{"@language":"ja","@value":"頭頸部癌"}],"dc:publisher":[{"@language":"en","@value":"Japan Society for Head and Neck Cancer"},{"@language":"ja","@value":"日本頭頸部癌学会"}],"prism:publicationDate":"2013","prism:volume":"39","prism:number":"1","prism:startingPage":"77","prism:endingPage":"82"},"reviewed":"false","url":[{"@id":"https://search.jamas.or.jp/link/ui/2013279862"}],"availableAt":"2013","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=Preoperation%20diagnosis","dc:title":"Preoperation diagnosis"},{"@id":"https://cir.nii.ac.jp/all?q=Thyroid%20carcinoma","dc:title":"Thyroid carcinoma"},{"@id":"https://cir.nii.ac.jp/all?q=Ultrasound","dc:title":"Ultrasound"},{"@id":"https://cir.nii.ac.jp/all?q=Cystic%20thyroid%20nodules","dc:title":"Cystic thyroid nodules"},{"@id":"https://cir.nii.ac.jp/all?q=%E7%94%B2%E7%8A%B6%E8%85%BA%E5%9A%A2%E8%83%9E%E6%80%A7%E8%85%AB%E7%98%8D","dc:title":"甲状腺嚢胞性腫瘍"},{"@id":"https://cir.nii.ac.jp/all?q=%E7%94%B2%E7%8A%B6%E8%85%BA%E7%99%8C","dc:title":"甲状腺癌"},{"@id":"https://cir.nii.ac.jp/all?q=%E8%B6%85%E9%9F%B3%E6%B3%A2%E6%A4%9C%E6%9F%BB","dc:title":"超音波検査"},{"@id":"https://cir.nii.ac.jp/all?q=%E8%A1%93%E5%89%8D%E8%A8%BA%E6%96%AD","dc:title":"術前診断"}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1390845712978646016","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"ja","@value":"乳癌甲状腺転移の1例"},{"@language":"en","@value":"A case of thyroid metastasis from breast cancer"}]}],"dataSourceIdentifier":[{"@type":"JALC","@value":"oai:japanlinkcenter.org:1001788627"},{"@type":"CROSSREF","@value":"10.5981/jjhnc.39.77"},{"@type":"CIA","@value":"130004940752"},{"@type":"CROSSREF","@value":"10.5106/jjshns.28.95_references_DOI_WxQkd1IiC7bydcc4A83CuGYdVm4"}]}
