Giant Cell Tumor of the Temporal Bone with Direct Invasion into the Middle Ear and Skull Base: A Case Report
Figure 2
Temporal bone computed tomographic scan shows soft tissue shadow from the bone destruction with massive extension to the epitympanum and ossicular chain (a). In the coronal section, the tumor invades the skull base, and the outline of the tumor shows osteosclerosis with decalcification (b). Magnetic resonance imaging of the head revealed a mass 3 cm in diameter at the left temporal bone that was unequally enhanced after intravenous gadolinium (c). At the coronal section, the border with the tumor and the left mandible head was indistinct. In addition, the dura mater of the middle cranial fossa showed enhancement (d).
