Meningiomas of the Jugular Foramen

Meningiomas are usually benign tumors that originate from the meningothelial arachnoid cells that tend to cluster around the tips of the arachnoid villi. Their preferential site corresponds closely with the location where arachnoid villi are most frequently encountered.55-57 Therefore, the most common location for meningioma is the parasaggital area, the lateral cerebral convexities and the sphenoid ridge. The jugular foramen is an uncommon site for meningioma. Apart from the jugular foramen, other predilective sites of origin of meningiomas within the temporal bone are the internal auditory canal, the geniculate ganglion, and the sulci of the greater and lesser petrosal nerves.58-60
