Figure 1.4.10 Osteoma (Canine) CT & MR
2y MC Golden Retriever with cranial mass.
There is a smooth, dense production of bone
centered on the parietal bone and expanding
both intracranially and extracranially. The
mass is hyperattenuating and uniform on CT
images (a). On MR images, the mass effect is
evident with compression of the brain and
lateral ventricle next to the mass (b,c), as
well as displacement of the falx cerebri to the
right (d). There is T2 hyperintensity of the
white matter next to the mass, (b) indicating
edema.
