case_images: Magnetic resonance imaging (MRI) examination at clinical onset. (a and b) Coronal fluid-attenuated inversion recovery. A focal high signal intensity at the soft subgaleal extracranial structures in the right parietal bone is well depicted (white arrow). (c and d) Coronal Dixon T1-weigthed images after Gadolinium-DTPA administration. The diploic lesion shows intense and homogeneous contrast-enhancement. Fat suppression technique well demonstrates the involvement of the galea (white arrows) and the subjacent dura mater (red arrows). A slight contrast-enhancement inside the surrounding diploe, next to the main lesion, was present.

case_images: A slight contrast-enhancement inside the surrounding diploe, next to the main lesion, was present [Figure 1].
case_images: Computed tomography (CT) scan examination. (a) Volume rendering technique reconstruction; (b and c) Coronal multiplanar reconstruction with bone algorithm. An osteolytic area, with jagged edges, at right parietal bone is well depicted by CT scan.

case_images: Slightly suffusion in the near soft tissues was also present [Figure 2].
case_images: Computed tomography (CT) and magnetic resonance imaging (MRI) at 1-year follow-up showing a complete regression of the lesion. A, CT scan showing a minimal bone irregularity; (b and c) postcontrast T1 WI-weighted MRI images showing a complete regression of the lesion with a normal inner and outer cortical tables. Only a slightly contrast-enhancement of the parietal diploe was observed at the pathological area (white arrow).
