A member asked:
How small are intracranial tumors that don't show some kind of effect on a ct scan. if they are small would they be low grade/benign?
A doctor has provided 1 answer
Hard to say: Many tumors even of moderate size can be somewhat difficult to see on a noncontrast ct scan. Would not necessarily be low grade or benign. If there are multiple actual tumors in the brain, the most likely diagnosis is metastatic disease from another tumor. An MRI with contrast should be obtained.
