A 54-year-old man was repeatedly told by others during the last few years that he had a bulge on the left side of his head. When he noted a tender soft point in the middle of the bulging area, he consulted a neurologist. There was no history of headaches, scalp irradiation, or head trauma.

The physical and complete neurological examination results were unremarkable. Computed tomography of the brain showed a left, hyperdense, partially calcified frontal lesion with a frontal bony base (Figure 1A). Intense hyperostosis of the parietal bone with a soft tissue density inside was also noted (Figure 1B-D). Adjacent to the hypertrophic skull lesion, the cerebral cortical sulci were narrowed indicating local edema (Figure 1A).
