My 12 yo son was dx with an oligodendroglioma in his left occipital lobe almost 5 years ago when he presented with uncontrolled seizures despite being medicated. He has been through 2 resections and is currently on wait and watch. His neuro is also watching an area in his thalamus. There is a “lesion” that was first seen on the scans after the second surgery—it has not changed. The original tumor has shown slow growth since the second surgery. My concern is that my son just told me that his right hand has started shaking today when he is holding something like a cup. He showed me and there is a noticeable tremor. I don’t want to attribute everything to the tumor, but am hoping for some reassurance that it is most likely something else.
