Question: I had an MRI done yesterday to rule out a neurological cause for persistent dysphagia, and my GP called with the results. The MRI found a 3mm nonspecific heterogeneous t2 signal in the pons. The report recommends a follow up MRI with contrast in 3-6 months. I asked a neurologist on this site today about it, but was told he needed the report, which I don’t have. I asked subsequent questions that went unanswered. 1) What is a nonspecific heterogeneous t2 pons signal, in layman’s terms? 2) Is the pons an area of the brain likely to cause dysphagia, or would this be something unrelated, found by accident? 3) Why would the radiologist recommend waiting 3-6 months for the contrast MRI? 4) Is it anything to worry about? The neurologist from this site mentioned MS and demyelination. Scary!

Brief Answer:
Lesions may be due to demyelination(MS),ischemia etc.

Detailed Answer:
Hello,
Thanks for writing to Healthcaremagic,
I've gone through your query and understand your concern,

You are rightly suggested for follow up MRI.
It is important to see progression of lesions.
Heterogeneous signal on T2 weighted images may be due to demyelination,ischemia etc.
Normally there are no focal focal bright lesions on T2 weighted images.
Pons lesions may cause dysphagia.
It is important to see lesions in other areas of brain like peri ventricular region,corpus callosum of brain.
You may also need clinical correlation and further tests for multiple sclerosis.

Get well soon.

Hope I have answered your query.
Further queries are most welcome.

Take Care

I was recently diagnosed with lichen sclerosis. I find it difficult to see where to apply the strong cortisone cream I have been prescribed due to my pubic hair. Given that this condition may require treatment for the rest of my life, I am considering having all of my pubic hair lasered away permanently. Do you think this would impact negatively on this condition, to have laser on the skin where I have the lichen sclerosis, as well as everywhere else?

I recently had a liver enzyme test and the numbers were elevated. I had what I thought was the flu; vomiting etc. and close to 2 weeks when I wasnt better I went to see a physician and they ordered blood work finding the elevated enzymes. I RARELY drink alcohol and hadnt had any for at least a month or more before I was ill. They followed up with Hepatitis test, all were normal and negative for A-C. I did have the test re-ordered a week later and my levels are now within normal limits. Can the flu cause elevated liver enzymes? What would cause these numbers to fluctuate? I have Scleroderma (systemic sclerosis) and Im wondering if I should contact my rheumatologist about the one time elevated enzymes?
