Learning objectives To review the various ways in which non-odontogenic jaw lesions manifest in adult and pediatric population. To describe how non odontogenic jaw lesions adjacent structures, and the best way to recognize them through their imaging characteristics using orthopantomography (OPG), ultrasound (US), computed tomography (CT) and resonance magnetic (MRI) studies. To illustrate the main imaging features and to highlight associated injuries with-own experienced images from our database images.
Read more Background Non-odontogenic jaw lesions represent a wide spectrum of pathologies that include benign inflammatory/infectious lesions, as well as more aggressive malignant lesions such as tumors. The classification of non-odontogenic mandibular lesions must be taken into account according to their histology since they may have a hematological origin (plasmacytoma), derived from fat (lipoma), neoplastic (osteosarcoma...) etc.The following is a list of the lesions that will be discussed below, categorized according to their histological origin: Benign Mesenchymal Lesions:    - Fibrous Lesions:     - Fibrous Dysplasia   - Lipomatous Lesions:     -...
Read more Findings and procedure details Fibrous Dysplasia of the mandible is a benign, developmental bone disorder characterized by the replacement of normal bone with fibrous connective tissue and irregular bone trabeculae. It most commonly presents in children and young adults and iit may cause facial asymmetry, tooth displacement, or malocclusion.1.OPG: Ground-glass opacity, bone expansion.2.US: Hypoechoic, heterogeneous, with possible shadowing.3.CT: Ground-glass density, cortical thinning, bone expansion.4.MRI: T1WE (hypointense),T2WE ( Variable, mixed signal, possibly hyperintense in areas) with mild to moderate heterogeneous enhancement. It is a benign tumor...
Read more Conclusion There are various types of non odontogenic jaw lesions that have diverse histological origins. Early recognition of these injuries is crucial to prevent potential complications associated with inappropriate treatment and, in some cases, can help narrow the differential diagnosis. A thorough understanding of the nature of the lesions, along with the patient’s clinical context and whether they exhibit benign or malignant behavior, is crucial for the accurate diagnosis of non-odontogenic jaw lesions.
