Head to Head: Central Skull Base Mass

In the head to head series, I show you two different patients with two different diseases, but a similar radiologic appearance. Today's patients both have a mass in the upper nasopharynx, involving the skull base

Thank you so much! You show truly difficult cases and provide a clear explanation

thanks for sharing, i never thought about arterial narrowing as a way to navigate this ddx, i’d be curious to hear your thoughts on how inflammatory pseudotumor fits in

[@ENT_Imaging]

Pseudotumor affects younger patients and, in this location, is more rare than either of the other two diagnoses. In fact, I haven't encountered a case in the central skull base (although I'm sure it exists). The destructive nature of both infection and tumor should help to distinguish them.
