Discussion
The relapse involves massively the pterygo-maxillary fossa
including the lateral and medial pterygoidsmuscles
causing the trismus.There is a perineural extension along
the ways of the V2 (enlarging the foramen rotundum) and V3
(foramen ovale) up to the Meckel's cave.
Unfortunately, in spite of multiple chemotherapies, the
evolution was bad and the patient is now in end-stage
of disease.
