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.

A slight contrast-enhancement inside the surrounding diploe, next to the main lesion, was present [Figure 1].
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.

Slightly suffusion in the near soft tissues was also present [Figure 2].
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).
