Pantopaque is an oil-based contrast medium that used to be used for myelography. Its generic name is iodophenylundecylic acid and it was first used in 1944 and was officially discontinued in 1988 6.

The iodine moiety of the compound causes high attenuation on radiography and CT 6.

Its major drawback was the extremely slow resorption, with persistent material lasting decades 6. Complete removal through aspiration was usually impossible after a procedure, and the remaining droplets could lead to chronic irritation and severe arachnoiditis.
