Endoscopic Resection of Skull Base Teratoma in Klippel-Feil Syndrome through Use of Combined Ultrasonic and Bipolar Diathermy Platforms

Figure 2

CT angiogram (CTA) imaging of pedunculated skull base lesion. (a) Coronal CT slice at level of the bilateral sphenoid sinuses (S), with tumor pedicle arising between sinus cavities, at typical site of intersinus septum. The  cm tumor (T) is composed of heterogeneously dense material, with suspected low-density (dark) fat seen. (b) CTA in sagittal view, showing relationship of tumor pedicle extending between anterior sphenoid sinus (S) and posterior clivus (C). Arrow shows the diminutive artery coursing through the pedicle, without direct communication with the ICA and vertebrobasilar system (not shown).
