Missy, Thanks for responding! The lingo I am looking at in the MRI report says the the lesion (VM) extends to the infratemporal fossa with suggestion of extension into the pterygopalatine fossa. The report also says that the lesion involves the masticator space and it extends to the oral cavity. Ok. Please help me. I am trying not to panic but I looked up some of the lingo and wasn't getting a good feeling from the info. HELP!
