Chronic lacunar infarct in the midbrain?

I have been experiencing various progressive symptoms suggesting a brainstem lesion over the last six months.
MRI study of the head was done a few days ago and were reported by the radiologist to show no anomalies and I have been scheduled for further studies. However, while studying the images I found a small lesion in the upper midbrain locating around the area of medial lemniscus and substantia nigra which to my knowledge would indicate a chronic lacunar infarct. The lesion is most prominent in the T2 sequence image. I have made the images available at Dropbox.

T2 FLAIR

Does the anomaly shown in the MRI images indicate a chronic or subacute lacunar infarct?
