[|Human|] My significant other just returned from an mri evaluation of his lower back and kidneys. He s been having lower left sided back pain for a few months worse after power walking or standing on his feet. He s also had irregular urination from hardly any to too much, MRI shows spot on liver. All other tests have been negative. They want him to have a cat scan with injected dye. He s 68, thin. eats healthy and exercises. What could this be?
[|AI|]  Hi, In most cases, these spots are benign growths such as cysts or hematomas. Hematoma is very small and this can't cause such symptoms unless larger than 10 cm.  He should do an MRI scan or liver biopsy to find what type of lesion it is.  Less common this may be malignant issues such as hepatocellular carcinoma. His abdominal pain may not be related to liver spots at all.  It may always be a sign of some other issues such as IBD or gastritis. If these are just simple liver cysts then I don't think this is causing his symptoms. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
