ABSTRACT
Sinus mycetoma is a dense accumulation of hyphae that form a rounded mass within the mucosal confines of a paranasal sinus. The aim of this study was to present a case series of three patients with maxillary sinus mycetoma and to describe their radiographic presentations. Three cases are presented. The first two, a 44-year-old woman and an 88 year-old man, both diabetics, were referred to maxillofacial treatment by other specialties. They both had a bad odor of unknown origin on the facial level and their respective computerized tomographies revealed a unilateral opacification of the maxillary sinus with a region of greater radio-opacity. The third case is a 31-year-old woman with a history of a severe facial trauma who had undergone surgery and for whom orthognathic surgery had been planned to correct side effects. In addition to the orthognathic surgery, the removal of the lesion that appeared opacified in the pre-surgery scan was planned. She showed opacification of the maxillary sinus and during the intraoperative stage, tissue of a whitish-gray appearance was detected on the maxillary sinus. The lesion was completely removed and the result of the histopathological study was sinus mycetoma. The patients evolved favorably and the symptomatology disappeared completely. The growing occurrence of mycetoma and the lack of information on it make publicizing this pathology fundamental so it can be considered as a differential imaging, clinical, and pathological diagnosis and in that way receive adequate and opportune treatment.
RESUMEN
El micetoma sinusal es una patología de origen fúngico, que afecta a pacientes inmunocomprometidos, capaz de desorientar en su diagnóstico por su clínica y expresión imagenológica particular. El objetivo de este estudio es presentar una serie de tres casos con micetoma en el seno maxilar y describir su presentación imagenológica. Se presentan tres casos. Los dos primeros, una mujer de 44 años y un hombre de 88 años, ambos diabéticos y derivados a atención maxilofacial por otras especialidades. Coincidía un mal olor expelido de origen desconocido a nivel facial y en sus respectivas tomografías computarizadas se observó velamiento unilateral del seno maxilar con una zona de mayor hiperdensidad. El tercer caso corresponde a una mujer de 31 años con antecedente de trauma facial severo operado, a la cual se le planificó cirugía ortognática para corregir secuelas. En conjunto con la cirugía ortognática, se planificó la biopsia excisional de una lesión hiperdensa que se presentó en el escáner pre-quirúrgico; en el intraoperatorio se pesquisó tejido de aspecto blanquecino grisáceo en el seno maxilar. A todos los pacientes se les realizó la exéresis total de la lesión y el estudio histopatológico dio como resultado micetoma sinusal. Los pacientes evolucionaron favorablemente, desapareciendo por completo la sintomatología. La creciente incidencia del micetoma y el desconocimiento sobre el mismo hacen que sea fundamental la difusión de esta patología para ser considerada como diagnóstico diferencial clínico y patológico, y realizar así un tratamiento adecuado y oportuno.
