RESUMEN
Introducción: El quiste óseo simple (QOS) es un pseudoquiste intraóseo, de etiología desconocida que representa el 1% de los quistes maxilares. Radiográficamente se observa una imagen radiolúcida de bordes bien definidos, irregulares o festoneados. Su tratamiento consiste en la exploración quirúrgica y curetaje de paredes óseas. En pocas ocasiones se ha descrito resolución espontánea. El propósito de este documento es presentar un caso de QOS de resolución espontánea y realizar una revisión de literatura.Reporte de caso:Mujer de 12 años consulta para evaluación odontológica de rutina. En radiografía panorámica se observa lesión radiolúcida entre raíces de dientes 4.4 y 4.5, de límites bien definidos corticalizados. Se complementó con tomografía computarizada de haz cónico, donde se observó adelgazamiento de tablas óseas. Se realizó un diagnóstico presuntivo de QOS. Se controló a los 3 y 3,5 años observándose hueso de leve mayor densidad que el hueso circundante.Materiales y métodos:Se realizó una revisión de literatura sobre QOS de resolución espontánea en PubMed, Scopus y Web of Science, relacionando los términos libres simple bone cyst spontaneous resolution jaws y sus variantes.Resultados:Se encontraron 13 casos de QOS de resolución espontánea. Las características clínicas y radiográficas de los casos coinciden con la literatura. El 54% de los casos tuvo resolución espontánea en un periodo menor o igual a 5 años.Conclusión:En el presente caso se realizó el seguimiento radiográfico del paciente, demostrando que controlar en el tiempo puede considerarse como tratamiento, ya que la lesión podría resolverse espontáneamente.(AU)
Introduction: Simple bone cyst (SBC) is an intraosseous pseudocyst, of unknown etiology, which represents 1% of maxillary cysts. Radiographically, a radiolucent image with well-defined, irregular or scalloped edges is observed. Treatment consists of surgical exploration and curettage of bone walls. Spontaneous resolution has rarely been described. The purpose of this paper is to present a case of spontaneous resolution of SBC and perform a literature review.Case Report:A 12-year-old woman attends to a routine dental evaluation. Panoramic radiography shows a radiolucent image between roots of teeth 4.4 and 4.5, of well-defined corticated borders. It was complemented with cone-beam computed tomography examination, where thinning of cortical bone was observed. A presumptive diagnosis of SBC was performed. Controls at 3 and 3,5 years were performed and bone of slightly higher density than the surrounding bone was observed.Materials and methods:A literature review on SBC of spontaneous resolution was performed in PubMed, Scopus and Web of Science, relating the free terms simple bone cyst spontaneous resolution jaws and their variants.Results:13 cases of spontaneous resolution of SBC were found. The clinical and radiographic characteristics of the cases coincide with the literature. 54% of cases had spontaneous resolution in a period of 5 years or less.Conclusion:In the case presented, radiographic follow-up of the patient was performed, demonstrating that following-up can be considered as treatment, since the lesion could resolve spontaneously.(AU)

An idiopathic bone cavity (IBC) tends to rise as an abnormality in osseous growth, a degenerating tumoral process, or triggered by hemorrhagic trauma. This paper describes the interpretation of an IBC and its progression over one year. The patient's initial radiographic images showed well-defined multilocular radiolucency located at the right mandibular molar region, extending between the teeth and the mandibular basis. No clinical symptoms were present, and the course of the mandibular canal was not altered. The lesion was not initially biopsied due to the patient's dental anxiety. Over one year, the radiolucent area extended anteriorly and thinned the lingual and buccal cortices. Prior radiolucent areas changed to granular-appearing bone. The diagnosis was based on a fine-needle aspiration biopsy. The appearance of an IBC is not unique; its benign nature should be differentiated from multilocular or fibro-osseous lesions by a careful interpretation of clinical and radiological perspectives.
RESUMEN
El quiste óseo solitario de la mandíbula es una cavidad intraósea sin recubrimiento epitelial, considerado un pseudoquiste, ha recibido diversas denominaciones debido a su etiología y patogenia inciertas como quiste óseo traumático, quiste óseo solitario y quiste óseo idiopático. Clínicamente suele ser una lesión asintomática, muestra bordes festoneados cuando está localizado entre las raíces dentales, es una cavidad vacía pero puede contener sangre, fluido seroso o serohemático y es descubierta en exámenes radiológicos de rutina. En este artículo se presenta un caso de quiste óseo solitario localizado en el cuerpo mandibular que acomete a un paciente femenino de 17 años de edad con tetralogía de Fallot, revelando aspectos clínicos, diagnósticos e imagenológicos y tratamiento.
Solitary bone cyst of the mandible is an intra-osseous cavity lacking epithelial lining considered a pseudocyst. Due to its uncertain etiology and pathogenesis, it has received several names such as traumatic bone cyst or idiopathic bone cyst. From a clinical perspective, it is oftentimes an asymptomatic lesion, with festooned borders when located between dental roots. It is an empty cavity but might contain blood, serous or serous-hematic fluid and can be perceived in routine X-ray examinations. The present article describes the case of a solitary bone cyst located in the body of the mandible of a 17-year old female patient. Afflicted with Fallot's tetralogy. Clinical, diagnostic and radiologic aspects as well as treatment are described.
