[|Human|] (34yo Female) MRI showed well-circumscribed, low attenuating, hypoechoic liver mass. Grew from 1.2cm to 1.8cm since last MRI (18 months ago). Initially my dr wasn t concerned (it was found accidentally during an MRI for kidney issues) but he wasn t thrilled that it had grown on my most recent scan. He is debating sending me to GI. Thoughts on what this could be? Hemangioma? Can cancer be ruled out due to the characteristics?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion it is more favoring benign etiology. Following are the benign causes for slowly enlarging liver mass. 1.  Liver cyst2.  Liver abscess3. Hematoma etc. Possibility of malignant lesion is less likely because mass is well circumscribed and low attenuation, hypoechoic. This is less likely finding in malignant mass. But we need to get done biopsy of the lesion to confirm the etiology. So consult GI doctor and get done biopsy to rule out above-mentioned causes.
