Review of imaging modalities and radiological findings of calvarial lesions

Figure 24  Calvarial solitary lytic metastasis of endometrial carcinoma (Malignant mixed mullerian tumor) in sixty-two years old female patient. A: Axial computed tomography on the bone window shows a lytic mass lesion (arrows) extending to the scalp, destroying the inner and outer table of the left frontoparietal bone; B: Axial 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET-CT) shows intense 18F-FDG uptake (SUVmax: 30.13) in the left frontoparietal mass lesion (arrows); C: Apparent diffusion coefficient map shows mild diffusion restriction in the mass; D: Hypointense hemosiderin deposits secondary to bleeding or calcifications products in the mass shows on axial enhanced susceptibility weighted angiography images; E: Coronal contrast enhanced BRAVO image shows heterogeneous, occasionally linear contrast uptake in the mass with periosteal reaction infiltrating the cerebral parenchyma; F: Axial fat-saturated contrast enhanced T1-weighted image shows intense heterogeneous contrast uptake in the metastatic mass (arrows).
