“…While patients with jaw lesions are usually older, all age groups have been affected [4]. A painful swelling is the most common clinical presentation, with paresthesia and loosening of teeth also frequent findings [5,6]. Radiographically, the radiating pattern of trabeculation noted within the current case supported consideration of osteosarcoma, although only 25% of gnathic osteosarcomas demonstrate a radiating or ''sunburst'' pattern of osteoid production [4].…”

“…Formation of calcified material above the alveolar crest was also considered suspicious for this entity. On the other hand, another important radiographic hallmark of gnathic osteosarcoma, widening of the periodontal ligament space [5,6], was absent. In contrast, in our patient the periodontal ligament space of tooth #19 appeared obliterated by the process.…”

“…A thorough radiological examination is required to come to a prompt diagnosis of osteosarcoma. Increase in the awareness of the diagnostic features may lead to an early diagnosis and in doing so may improve the prognosis [6]. The final diagnosis can only be provided by histology and it should be kept in mind that osteosarcoma may mimic certain tumours histologically from which they originate and hence, it is essential to correlate the radiological and histological findings before arriving at a particular diagnosis.…”

“…Les deux aspects peuvent également coexister [1,11] . Classiquement, on retrouve un aspect caractéristique, bien que non pathognomonique, en « feu d'herbes » ou en « rayons de soleil », dû à la réaction périostée et à la production de tissu ostéoide en périphérie de la tumeur [1,11,12] . D'autres signes radiologiques peuvent être associés à l'ostéosarcome comme : -un élargissement du desmodonte secondaire à un envahissement tumoral, -une résorption radiculaire sur les dents en rapport avec la tumeur [1,4] .…”

“…La tomodensitométrie permet d'évaluer la taille de la tumeur, ses limites, la présence ou non de calcifications intra-tumorales, la densité de la tumeur avant et après injection par voie intraveineuse de produit de contraste. Elle permet aussi de préciser [12,13] . L'imagerie par résonance magnétique est préfé-rable à la tomodensitométrie pour l'évaluation de l'extension tumorale aux tissus mous, aux structures intracrâniennes, à la fosse infra-temporale ou à la cavité orbitaire [13] .…”
