Pdf Summary
This study guide is intended for use with Test 210094 about the anatomy and diseases of the greater wings of the sphenoid bone, part of the RadioGraphics Online SA-CME program. To earn credit for the activity, participants must complete the corresponding online test on the RSNA website. The guide includes several key questions about the anatomy and associated structures of the greater wings of the sphenoid bone.<br /><br />1. The anatomic landmark between the greater wings of the sphenoid bone and the lesser sphenoid wings is the superior orbital fissure.<br /><br />2. The foramen that allows passage to the mandibular division of the trigeminal nerve (V3) and the accessory meningeal artery is the foramen ovale.<br /><br />3. The ossification center of the central skull base that represents the embryologic origin of the greater wings of the sphenoid is the alisphenoids.<br /><br />4. In CT scans, the finding that suggests arrested pneumatization is the presence of thick pseudotrabeculae with a “cotton” appearance.<br /><br />5. In imaging related to juvenile angiofibroma, the presence of flow voids suggests the vascular nature of the condition.<br /><br />These questions provide a structured approach to understanding the key anatomical and pathological aspects of the greater wings of the sphenoid bone. Such knowledge is essential for medical professionals dealing with imaging and diseases related to this part of the skull. Participants are encouraged to use this guide alongside the online materials for a comprehensive understanding and completion of the CME activity.
