Paciente do sexo feminino, 54 anos, apresentava queixa de lacrimejamento excessivo por olho direito ha 12 anos. Apos quatro anos, apresentou obstrucao progressiva das fossas nasais. Ha um ano surgiu abaulamento proximo ao canto interno do olho direito, doloroso a compressao. Ao exame fisico, havia epifora em olho direito e lesao de consistencia cistica, com hiperemia da pele sobrejacente proxima ao can-to medial do olho direito, de 1,2 cm de diâmetro (fig. 1A). A lesao nao apresentava drenagem a expressao, tampouco regurgitacao de secrecao pelos canaliculos. A rinoscopia anterior, foi visualizada obstrucao total da fossa nasal direi-ta e, a esquerda, reducao de sua luz por desvio septal. Tomografia mostrou lesao com consistencia de partes moles na localizacao do etmoide, seio maxilar e fossa nasal direi-tos, determinando erosao da lâmina papiracea com com-pressao do reto medial e deslocamento do globo ocular, alem de erosao e deslocamento do septo nasal para a esquerda, compativel com mucocele (fig. 1B). Sendo assim, optou-se por tratamento cirurgico, que revelou bolsa pre-enchida por material mucopurulento e originaria do saco
