Lateral (a) and frontal (b) skull radiographs showed a sclerotic lesion in the left parieto-occipito-temporal cranial vault. Computed tomography (CT) demonstrated a solitary osseous-based lesion with marked spiculated periosteal reaction (c) and mildly hyperdense soft tissue component abutting the inner and outer tables of the left cranial vault (d).
