Female, 53 years old, with history of brain mass/skull lesion. Evaluate for change. A heterogeneously enhancing, expansile mass is redemonstrated centered on the calvarium, just to the left of midline at the cranial vertex. The lesion measures 48 mm AP, 58 mm TV, and 32 mm CC showing no significant change from the prior examination.The lesion displaces both the inner and outer tables of the skull. It indents the underlying left parietal lobe, along with the cortical veins and the superior sagittal sinus which nevertheless appear patent. No evidence of parenchymal invasion or parenchymal edema is seen. No other enhancing calvarial lesions are detected . Minimal scattered small foci of T2 hyperintensity are seen within the cerebral white matter, a stable and nonspecific finding. No evidence of significant parenchymal edema or restricted diffusion is seen. No abnormal extra-axial fluid collections are detected. The ventricles are normal in size and morphology.
1.No significant change in the size or appearance of a large, expansile mass centered on the calvarium at the cranial vertex.2.As before, the lesion indents the underlying brain parenchyma, but there is no evidence of brain invasion or parenchymal edema.3.No other concerning osseous lesions are seen. Evaluation of the brain parenchyma is unremarkable.
