And the MRI reveals…..NOT MUCH

Today I had an MRI scan of the brain which was originally scheduled for my regular monitoring to make sure there is no recurrence of my benign Brain tumour.

This opportunity was also being used to look for any neurological abnormalities which might explain why the left side of my face has numbed up in the last couple of weeks. (see my previous post for details)

When my neurosurgeon, Dr David Walker examined the images he found:

a) no sign of recurrence in the area of the previous surgery. Yippee - That means that I have now been tumour-free for seven years!!!

b) no sign of anything in the area of the Trigeminal nerve (the nerve responsible for sensation in the face) which might explain my mouth and face numbness.

c) There was a faint artefact on the image in an “inoperable area of the brain stem” which Dr Walker noticed but he will have to consult with the radiologist to decide if it is significant or not.

Regardless of the outcome of point c, he has scheduled a followup MRI and consultation with him in six weeks time.

Strange happenings after dental work - Is this a symptom of Tumour recurrence???

One of the problems of living with a brain tumour is the constant worry that the thing is growing again. To make sure that is not happening I have regular 3 monthly MRI scans which are reviewed by my neurosurgeon. But aside from that, occasionally something strange will happen and you can’t help jumping to the conclusion that it’s the brain tumour again. For example, see my post from August 3 2012

Well following some dental work recently, some strange numbing has occurred which not only makes me nervous but the doctors are quick to point the finger at the brain tumour when they read my medical history.

A week ago the left side of my mouth became numb. It started on Thursday and felt like the injection the Dentist had given me a week before in the upper left jaw was repeating its effect on me! Very weird stuff, but that was my first thought. I was hoping it was some known (if rare) side-effect of dental anaesthetic. Either that, or it had to be something neurological like a bleed (i.e. stroke), or something associated with the old benign brain tumour. I was hoping it would go away over the long weekend but when it was still numb on Tuesday morning I got back into the dentist at short notice for them to have a look at it. They told me that they had never seen such a thing before, given that the anaesthetic had worn off as usual after the original injection and did not"repeat" on me until a week later. The Dentist told me I should go see my  GP about it. The GP thought that possibly the Dentist might have damaged a nerve with the tip of the needle, so referred me to a maxillofacial surgeon at the Wesley Hospital who specialises in that part of the body. I had that appointment and, unlike the GP, he does not think it is likely to be from  the Dentist's needle hitting a nerve. Unfortunately, he is thinking it is more likely to be something neurological, especially given my history with a benign brain tumour.

As it turns out I already have an MRI of the brain lined up for this week for my regular checkup with my neurosurgeon, so the maxillofacial doctor is writing to my neurosurgeon about this new problem and asking him to see if he can spot anything in the images. If he does, it is quite possible that I may need brain surgery again! The maxillofacial doctor wants to see me again on 23 May.
