Cisto nasolabial: apresentação de um caso e descrição em imagens por TC e RM

Abstract: O cisto nasolabial é um cisto não odontogênico raro que se desenvolve na região inferior da asa nasal, com patogênese ainda incerta. Esta lesão, que possui crescimento lento e dimensões variáveis (1,5-3cm), caracteriza-se clinicamente por uma tumefação flutuante na região do sulco nasolabial ao redor da asa do nariz, causando uma elevação do lábio superior. Seu diagnóstico pode ser feito basicamente pelo quadro clínico e, se necessário, complementando-se com exames auxiliares por imagens. O presente trabalho r… Show more

“…These cysts are unilateral in 90% of cases and 10% bilateral. Unlike our case, they are seen commonly in black women in the 4th to 5th decades of life [3]. Their extra-osseous origin and location recognize nasolabial cysts under the alae nasi [10].…”

“…Later, in 1951, the term nasolabial cyst was introduced by Rao [10]. This term has been regarded as more accurate since the cysts are situated wholly within soft tissue, unlike nasoalveolar cysts, which typically cause a maxillary bone defect [3,8]. It has recognized because of the complex discussions of its pathogenesis, as well as its characteristic clinical presentation [11].…”

“…[1][2][3] The pathogenesis of NC remains unknown, but has been attributed to epithelial remnants retained in the nasolacrimal duct extending between the lateral nasal process and maxillary prominence. [3][4][5][6] Clinically, NC presents as an asymptomatic soft swelling in the upper labial mucosa in the area of the nasolabial fold, which may cause facial asymmetry. [1][2][3][4][5][6] Pain may be experienced by patients with secondary infection due to nasal obstruction induced by the cyst.…”
