What if a recent mri on brain read venous differnetial in the opptiucal lobe, could it be a brain tumor starting have been having trouble speaking?

occipital venous: It could be venous angioma, metastatic lesion, a-v malformation. It can cause construction apraxia- means - inability or difficulty to build, assemble, or draw objects.If you have speech problem which could be expressive, receptive or mixed aphasia, slurred speech, but location of lesion could be thalamus, frontal lobe, parietal lobe, transcortical area, but not occipital lobe.

Question unclear: I'm sorry, your question is just not clear and can't be sensibly answered. A tumor in one of the occipital lobes is not likely to cause difficulty speaking unless it was large enough to be clearly visible on an mri. I think "venous differential" is a mis-quotation. Perhaps the report read "deep venous anomaly" or "venous hemangioma"? These are benign conditions. Ask your doctor to clarify.
