Computed tomography of odontogenic myxoma

Abstract

CT clearly demonstrated characteristic features of odontogenic myxoma. CT analysis may contribute to establishing a consensus regarding the interpretation of conventional radiographic appearances in odontogenic myxoma.

Odontogenic Myxoma with Diffuse Calcifications: A Case Report and Review of the Literature

“…Central odontogenic fibroma is much more collagenized, although there may be focal myxoid areas, and may produce small and scattered deposits of ''dentinoid'', an amorphous, eosinophilic material [5,16]. The case reported here is diffusely myxoid with extensive calcifications.…”

Characteristic features of the odontogenic myxoma on cone beam computed tomography

“…4,10,17 These characters explain the aggressive nature of the pathology. Although the borders of 14 (78%) subjects were well defined, 15 (83%) subjects showed an unclear margin in our study.…”

“…Some studies reported that these features suggest the invasive nature of the tumour radiographically and advised differentiating from metastatic lesions in the jaw and osteogenic sarcoma. 3,6,11,12 Koseki et al 10 reported that OMs tended to involve the alveolar process in tooth-bearing areas. 5 (33%) of 15 multilocular subjects scalloped between the roots and 9 (60%) subjects interrupted the integrity of alveolar ridge in this study.…”

“…Maxillary lesions often extend into the sinuses, while mandibular tumours often infiltrate the mandibular canal, which makes resection difficult and imposes high chances of recurrence. 3,10 Therefore, in order to establish a proper diagnosis and provide detailed information regarding the tumour extent, border and involvement with surrounding structures, the use of radiographs is required as a diagnostic and pre-surgical standard.…”

Fibromixoma odontogénico con mimetismo radiográfico de lesión ósea maligna. Reporte de caso

“…tos, dando apariencia de rayos de sol (2,15), lo que no debe ser confundido con reacción perióstica, como se observa en el osteosarcoma. La cortical también puede estar intacta pero adelgazada y expandida, permitiendo la clara identificación de los bordes lesionales (19). Koseki et al (19) usando tomografía computarizada para la evaluación de mixomas, señalan que los tabiques internos no son visibles en todos los casos y que cuando se observan no separan completamente la lesión en múltiples compartimientos.…”
