No. Tumours or similar appear as 'mass effect' in radiology reports. Also, if they'd found a tumour, you would have heard from them VERY quickly. The only thing of note is "focal area of abnormal attenuation", but you've not included the "impressions" portion of the MRI, so this could be anything from simply an imaging artefact, to evidence of migraine, or demyelination, etc. But we're just patients. It's best to go over these results with your doctor.
This was a CT scan, so the terminology used may be somewhat different. Doctors generally contact their patients quickly if something life-threatening turns up on a test. The best person to interpret the results is the doctor who prescribed the scan, so to set your mind at rest I urge you to give him or her a call.
Since MS uses MRIs as diagnostic tool, not CTs, this forum is not a good place for your question. You might try the general neurology forum, but please do simply ask your doctor. Good luck.
