Background and Objectives: To date, imaging characterization of non-rheumatic retro-
odontoid pseudotumors (NRROPs) has been lacking; therefore, NRROPs have been …

Objective Hemodialysis has been reported to be associated with retro-odontoid
pseudotumor (ROP), but its clinical characteristics have not been well described. The …
