ABSTRACT
Cholesterol granuloma (CG) is a foreign body reaction to the deposition of cholesterol crystals, usually found in association to chronic middle ear diseases, being highly uncommon in the paranasal sinuses. This article reports a case of CG in the maxillary sinus of a 22-year-old man, manifesting as a swelling on the right maxilla associated with pain and nasal obstruction. Computed tomography (CT) imaging showed complete opacification of the right maxillary sinus with cortical bone expansion and destruction. Incisional biopsy showed a solid mass filling the sinus and histological examination showed foreign body reaction to cholesterol crystals. The microscopic findings associated to tooth vitality, CT images and absence of a cavity during the surgical procedure were compatible with the diagnosis of CG of the maxillary sinus. Complete surgical excision of the mass under general anesthesia was suggested, but the patient did not return to conclude the treatment. CG must be included in differential diagnosis of diseases that cause opacification on the paranasal sinuses, especially sinusitis, and cystic and tumoral lesions.
RESUMO
Granuloma de colesterol (GC) é uma reação de corpo estranho a deposição de cristais de colesterol, usualmente encontrado em associação com doenças crônicas do ouvido médio, sendo bastante incomum nos seios paranasais. O objetivo deste artigo é relatar um caso de GC no seio maxilar de um homem de 22 anos de idade, manifestando-se como aumento de volume na maxila direita, associado a dor e obstrução nasal. Cortes de tomografia computadorizada (TC) mostraram opacificação completa do seio maxilar direito com expansão e destruição do osso cortical. A biópsia revelou uma massa sólida ocupando o seio maxilar e o exame histológico mostrou uma reação de corpo estranho aos cristais de colesterol. Os achados microscópicos associados à vitalidade dos dentes, imagens em TC e ausência de cavidade durante o procedimento cirúrgico foram compatíveis com o diagnóstico de GC do seio maxilar. A excisão cirúrgica completa da massa sob anestesia geral foi sugerida, mas o paciente não retornou para concluir o tratamento. O GC deve ser incluído no diagnóstico diferencial das doenças que causam opacificação dos seios paranasais, especialmente as sinusites e lesões císticas e tumorais.
