In addition to providing accurate anatomical location of the lesions, Computed Tomography (CT) scan can also provide valuable information about the extent of the disease in the preosseous stages, which may manifest as swelling and edema of the muscular fascia planes and muscular bundles.
MRI has a role in making the diagnosis in the early stage (preosseous stage).
Osteomas of the temporal bone probably develop in preosseous
connective tissue, which has a relatively thick subcutaneous layer and a rich blood supply.
Temporal bone osteomas probably develop from preosseous
connective tissue, but their etiology has not been established.
Osteomas are true neoplasms thought to arise from preosseous
