Ans:D. Fibrous Dysplasia.
Fibrous dysplasia
- It is an idiopathic skeletal disorder in which medullary bone is replaced by poorly organized structurally unsound fibro osseous tissue. Most commonly involved site is the posterior maxilla. In this condition, the normally radiolucent maxillary antrum may be partially or totally replaced by the radio-opaque lesion.
- Extra oral film taken in a case of maxillary fibrous dysplasia shows ground glass appearence. Intraoral film taken in this condition shows orange peel appearence.
- Fibrous dysplasia of the facial skeleton commonly involves the maxilla. It commonly involves one maxilla. CT scan shows a lesion that is confined to the bone with no soft tissue component. It is helpful in distinguishing fibrous dysplasia from a malignancy. Features of malignancy include osteolysis, destruction of sclerotic margins, and cortical destruction with soft tissue extension. The bony lesion shows a homogenous matrix with obliteration of maxillary sinus cavity.
