The radiographic finding of the left maxilla indicate towards:
Correct Answer: Fibrous dysplasia
Description: Imaging Features:
Location:
Fibrous dysplasia involves the maxilla almost twice as often as the mandible and occurs more frequently in the posterior aspect. Lesions more commonly are unilateral, except for very rare extensive lesions of the maxillofacial region that are bilateral.
Periphery:
The periphery of fibrous dysplasia lesions most commonly is ill-defined, with a gradual blending of normal trabecular bone into an abnormal trabecular pattern. Occasionally, the boundary between normal bone and the lesion can appear sharp and even corticated, especially in young lesions.
Internal Structure:
The density and trabecular pattern of fibrous dysplasia lesions vary considerably. The variation is more pronounced in the mandible and more homogeneous in the maxilla. The internal aspect of bone may be more radiolucent, more radiopaque, or a mixture of these two variations compared with normal bone. The internal density is more radiopaque in the maxilla and the base of the skull. Early lesions may be more radiolucent than mature lesions.
