Abstract(s)
O mucocelo é uma lesão quística, benigna, expansiva dos seios
perinasais. A sobreinfecção deste, designada de mucopiocelo, pode
levar a um período de crescimento rápido, com maior risco de
complicações.
Relata-se o caso clínico de uma doente do sexo feminino, 59
anos, que recorreu ao Serviço de Urgência após crise inaugural de
convulsão tónico-clónica generalizada, com queixas de aumento de
volume periorbitário direito e febre desde há 1 semana. Apresentava
à direita celulite orbitária e proptose ínfero-externa, com área de
flutuação na parte medial da pálpebra superior, oftalmoplegia e
quemose do olho direito acompanhada de rinorreia mucopurulenta.
Realizou TC que demonstrou volumoso abcesso subperiosteal direito,
ao nível da parede medial da órbita, tendo como ponto de partida
aparente as células etmoidais anteriores homolaterais e seio frontal
direito. Colocou-se a hipótese de mucopiocelo fronto-etmoidal.
Foi submetida a drenagem de urgência do abcesso e a cirurgia
endoscópica nasal com marsupialização da lesão fronto-etmoidal. Verificou-se resolução completa do quadro clínico. Apesar de consideradas lesões benignas, os mucocelos, apresentam
potencial destrutivo, principalmente se infectados, necessitando,
por vezes, de intervenção cirúrgica de urgência. A abordagem
endoscópica destas lesões reafirma-se como tratamento de eleição.
Mucocele is an expansive cystic benign lesion of the sinuses. The superinfection, called mucopyocele, may lead to a rapid growth period, more prone to complications. The authors present the case of a 59 years old female patient, who was admitted to the Emergency Service after inaugural generalized tonic-clonic seizure, with complaints of right periorbital swelling and fever since one week. Physical examination showed orbital cellulitis and infero-external proptosis, with an area of fluctuation in the inside of the right upper eyelid, chemosis and ophthalmoplegia of the right eye accompanied by mucopurulent rhinorrhea. CT demonstrated massive right subperiosteal abscess at the inner wall of the orbit, apparently starting from the ipsilateral anterior ethmoid cells and frontal sinus. A fronto-ethmoidal mucopyocele was suspected. She underwent emergency eye surgery with drainage of the abscess and endoscopic sinus surgery with marsupialization of the frontoethmoidal lesion. The patient experienced complete recovery. Although considered benign lesions, mucoceles present destructive potential, especially if infected, sometimes requiring emergency surgery. The endoscopic treatment of these lesions is reaffirmed as the treatment of choice.
