Vascular Lesions of the Skull Base: Correlation with Imaging
Purpose: Radiologic imaging plays a vital role in the recognition and diagnosis of vascular lesions of the skull base. The purpose of this educational exhibit is to provide an interactive MDCT and MRI imaging review of both common and unusual vascular lesions of the skull base with an emphasis on their imaging profile and clinical implications.
Content Organization: The normal foramina of the skull base will be reviewed through illustrations and images with discussion of contents. The MDCT and MRI appearance of vascular lesions of the skull base (including some arterial and venous lesions) will be presented with attention to their clinical significance. Some of the lesions presented will include: aberrant internal carotid artery, high-riding jugular bulb, jugular bulb dehiscence, persistent stapedial artery, persistent dorsal ophthalmic artery, and glomus jugulare/glomus tympanicum. A case-based, interactive quiz format will be used throughout the exhibit.
Summary: Familiarity with the imaging appearance of skull base vascular lesions is crucial to lesion diagnosis and plays a critical role in management and surgical planning.
