case_images: (a) Axial CT of the temporal bones showing a cystic mass of the left squamosal temporal bone disrupting the lateral cortex on the left (red arrow) and a well-pneumatized contralateral squamosal bone (green arrow). (b) T2-weighted axial MRI showing a fluid-filled mass at the left squamosal temporal bone. (c) T1 imaging reveals the lesion to be hyperintense and nonenhancing. (d) Postoperative CT showing complete resection with reconstruction via mesh cranioplasty.

case_images: Subsequent computed tomography (CT) scan of the temporal bone showed a 2.3 cm cystic lesion of the left squamosal temporal bone with disruption of the lateral bony cortex (Figure 1(a)). MRI revealed a nonenhancing, T2 hyperintense lesion (Figures 1(b) and 1(c)).
