Figures

Figure 1
Figure 1
A preoperative photograph (a), axial/coronal sections on preoperative computed tomography (b, c), and axial/coronal sections on preoperative magnetic resonance imaging (d, e) are presented. The computed tomography value for the inner area of the mass was 24 HU. T2-weighted magnetic resonance imaging showed a high signal intensity at the mass site.
Figure 2
Figure 2
Intraoperative photographs are presented. (a) After craniotomy. The arrow indicates the contents of the cyst. (b) After cyst capsule removal. The inside of the dotted line indicates a dead space. (c) The dotted line indicates an anterior pericranial flap that was elevated. (d) The dead space was filled with the folded anterior pericranial flap (arrow).
Figure 3
Figure 3
A photograph of the face 18 months after surgery (a), axial/coronal sections on preoperative computed tomography (b, c), and axial/coronal sections on preoperative magnetic resonance imaging (d, e) are presented. On 3-dimensional computed tomography (f), a bone defect of the orbital roof remained, but there was no ocular deviation. Magnetic resonance imaging did not show relapse. There was no postoperative bone deformity.
