SUMMARY:This report presents a 55-year-old woman who underwent 2 Teflon injections in 1971 for a patulous eustachian tube. The patient returned in 2006 with a bloody left otorrhea. A positronemission tomography-CT scan demonstrated a 2-cm hypermetabolic parapharyngeal mass, initially interpreted as a skull base tumor. Repeat neck CT confirmed a 2-cm hyperattenuated left parapharyngeal granulomatous mass. This is the first reported case of a Teflon granuloma presenting as a false-positive parapharyngeal mass.
있었다. Concha bullosa( 28.6%) 나 paradoxical middle turbin ate( 31.5%) 와 같은 비갑개의 변이, 내측 (36.3%) 혹은 외측 (3.7 %) 으로 전위되거나 기포화 (0.5 %) 된 구상돌기, Haller's cell(28.2%), 커진 agger nasi cell( 9.6%), 키진 사글포 (23.5%) 와 비중격만곡증 (24.1 %)0 1 전자에 속했고, onodi cell( 1. 4%) 과 지앙성 판막의 내측 함몰이 후자에 속했다. 이러한 변이들이 각 점막성 배출통로의 협소 또는 폐쇄를 돔반한 경우는 비전두 함요는 주로 커진 agger nasi cell(87예), 사글누두는 커진 사글포 (452 여 1) , Haller's cell(245여 1 ) , true concha bullosa(25여 1 ), 중비도는 내측전위된 구상돌기 (220여 1) , concha bullosa(157예), paradoxical middle turbinate( 126 여 1 ), 비중격만곡증 (93예), 접사함요의 경우는 상비 갑개의 기포화 (3예)에서 볼수 있었다. 결 론:해부학적 변이들의 임상적 의의는 첫째, 이들이 실제로 점막성 배출통로를 협소 또는 페쇄 시키고 있는지, 둘째, 협소 또는 폐쇄가 있다면 이차적으로 연관된 부비동에 염증을 동반하고 있는지 에 있으며, 세째로늠 일부 변이는 비내시경술시 심각한 합병증을 유발 할 수 있으므로 사전에 알고 유 의를 해야 하늠데 있다고 할 수 있다.
Purpose: The purposes of this article are to identify CT findings distinguishing nasal pOlyps , that are the most common cause of the nasal p 이 ypiod lesions, from other nasal cavity masses and to identify differential points between benign and malignant masses of nasal cavity.Materials and Methods: We classified 567 cases of pathologically proved nasal cavity masses into 4 different groups on CT accord ing to the sites of origin and surrounding bone changes.Result : The nasal p 이 yps were the most common cause of nasal cavity masses(515/ 567). Group 1 had a high diagnostic specificity for the nasal p이 yps (513/ 515 , 99.6 %) although inverted papilloma (8/ 522) and malignant melanoma(1 / 522) showed similar CT appearances.The representitive nasal mass of Group lI a was the inverted papilloma (15/ 24 , 66.5 % of the inverted papilloma).Group 111 pattern was seen in 3 cases of benign minor salivary gland tumor and 2 cases of pyogenic granuloma.Group IV suggested mal ignancy and thus was mostly observed in malignant tumors except 1 case of inverted papilloma and 1 case of granulomatous necrosis Conclusion : The differential diagnosis between nasal p 이 yps and the other nasal cavity masses is possible by characteristic bone changes and their sites of origin revealed on CT. In addition , it is possible to differ entiate malignant masses from benign in most cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
